An Analysis of Mechanical Properties and Flexural Behavior of Concrete Slabs Reinforced with H.F.R.P Reinforcements A Review

In the era of concrete, concrete is exposed to chemical, such as carbonation and chloride adulteration break down the alkaline barrier in the cement. Subsequently, steel in the concrete becomes corrosive. Such phenomena lead to erosion of concrete at the reinforcement level, cracking and spelling of concrete due to volume increase of steel reinforcement. Different methods were investigated to overcome corrosion by numerous researchers.According to A.S.T.M D792 13 standards the density of H.F.R.P bars have been evaluated the experimental value with 0.1mg precision. As per the standards, the H.F.R.P bars are weighed. Then, the H.F.R.P bar is immersed in distilled water at 230C and the wet weight of the bar is noted. The weight of the Sinker in immersed condition is also noted.The laboratory tests carried out to evaluate the physical and mechanical properties of the newly developed H.F.R.P bars and are compared with that of conventional bars. The bond properties of H.F.R.P bars with concrete is also determined. Finally, it explains the experimental investigations on the flexural behavior of concrete one way slabs reinforced with H.F.R.P reinforcements under static loading and are compared with conventional ones. The stress strain performance of the sand coated H.F.R.P bar is linear, lacking yield point up to the failure transverse shear strength is 3 times lesser than the tensile strength of the H.F.R.P bars. Thermal properties of fibers are substantially different in the longitudinal and transverse direction. Therefore the thermal characteristics vary between products according to the fiber, matrix and the fiber volume ratio. In this study the longitudinal Coefficient of linear thermal expansion is7.5 x 10 6 oC to 9x 10 6 oC. Whereas the transverse Coefficient of linear thermal expansion is between 15 x 10 6 oC to 20 x 10 6 oC. Load deflection graphs drawn exhibits the accordance between experimental and FEM ANSYS observations. The reduced deflection of FEM is due to the rigidness of meshing. The results also confer about the effect of tension stiffening and the bond slip. From the comparison it has been observed that experimental deflections vary from 1.03 to 1.37 times higher than the FEM deflections.

Design of Split or Two Piece Axle Shaft for Automotive Application

Axle is a key component in complete power transmission drive train. There are various types of axle shafts used in different type of vehicle and failure modes also of them are different. There are basic two types of axle shaft, one is used in single reduction axles and other one is used in hub reduction vehicles axles in other words double reduction axles . Hub reduction is nothing but the final drive reduction generally located near to wheels. Generally Axle shafts are being made up of medium carbon ally steel with through hardening treatment. Axle shaft connects differential with wheel rim in case of single reduction axle and with sun gear in case of double reduction axles. Axle shaft transmits torsion load from differential to the wheels and prime component to generate necessary traction to propel the vehicle.

Review on Planning and Scheduling of Construction Project by Management Tool Primavera P6

 Modern construction system has shown great potential in the field of the conventional construction system. The advantage of using new construction techniques for any type of construction is that the process takes no longer. The modern method of construction is defined as a way of working more effectively to achieve more while using less. The description lends itself heavily to offsite or modular construction techniques the method of prefabricating parts of building offsite before transporting and assembling them at their final location. Unlike traditional methods of construction is defined as a way of working more effectively. Poor construction management will cause the delay. Delay in the contracted project can result in penalties and adversely affect the reputation of the company. It is essential to manage the work within time. If construction time increases, construction cost also increases. It is necessary proper planning and management for construction work. Primavera p6 is a management tool. In this study primavera software help in the planning and scheduling of the project. Primavera gives better quality of project management process and easily understanding results.

Performance Study on California Bearing Ratio Values using Geosynthetics

The main use of geosynthetics or geofabrics is ensured in any given geotechnical engineering work or application. Sometimes, design and construction of pavement on weak soil creates many of the problems due to its load bearing capacity because of high axle loads vehicles on expansive wet soil subgrades, now we have many techniques to modify the properties of such soil. In this study we can perform the California bearing ratio testing over woven and nonwoven geotextile combined between soft subgrade and unbound gravel in an unpaved flexible pavement system is carried out experimentally on CBR testing arrangement. In order to improve the results we can take the reinforcement ratio is obtained based on the CBR load which is penetration relation of both soft subgrade gravel and soft sugared geotextile gravel separately for woven and nonwoven geotextile. After performing the CBR strength test on soil we can check how much geotextiles required to cover the soil according to the bearing strength of soil shows that the performance is improved after including woven and nonwoven geotextile. The construction of roads over soft subgrade soil is a challenge for any engineer to reduce the cost and then using of geofibers effects the cost of construction and duration of highway projects due to this sometimes rescheduled the construction work in many regions where soft subgrades are common over a large area. The strength of the subgrade mostly expressed in terms of California bearing ratio CBR , which is the ratio of test load to standard loads at a specified penetration by a specified plunger.If we use Geosynthetics or Coir fiber as a main component used in highway construction then it is economical because additive layers like asphalt, concrete and cement concrete are not used and saves the cost of these materials. The soil samples used in CBR test were prepared with two types of soil which are Clayey and sandy contains reinforced and non reinforced soil. The samples has the composition of three types of geotextiles with different characteristics i.e. 150, 200, 300 g m2 and depths or heights i.e. 10, 20, 30,50, 100 mm and it can be grouped into two forms i.e. one layered and two layered based on the sample materials in order to requirement or perform defined tests. Using of geofibers increases the bearing load capacity of soils, we can use one layer of geotextile used in wet soils and sandy samples. From last few years geo synthetics have joined the list of traditional civil engineering construction materials. In this whole study strength characteristics were studied using the California bearing ratio CBR test method.

An Assessment of the Prospects of Introducing Solar Energy in the UNEC Energy Mix

With the continued annual increase in the number of students and staff within the University of Nigeria Enugu Campus UNEC , the demand on energy has continued to rise. There is need for an efficient and regular power supple to meet the growing demands in order to ensure proper functioning of the academic environment. The Campus currently receives an average of about 5 hours of electricity from the national grid daily. This is due to the erratic power supple and inherent in the country, making learning conditions stressful, administration more tedious and the living conditions in the students and staff housing difficult. As an alternative the campus relies on fossil fuel powered generators which apart from high cost of maintenance, are grossly inefficient and constitute environmental pollution with the constant release of harmful gases and noise. The study investigated and assess the current state of energy supply within the various zones of the campus, and explored the potentials of introducing an efficient, safe and alternate source of power in the campus energy mix. It evaluates potential of solar energy installations and possible challenges associated with the University of Nigeria, Enugu Campus.

IoT Based Intelligent Management System for Agricultural Application

The growth of technology in any sector is not there in agriculture and this is a problem for India. The government has struggled to do anything for the farming sector which is in an exceptionally deplorable state. The pause in decision making also has led to Indias high rate of unemployment owing to the quality of the economy. The applications in well developed countries involve robotics, aircraft, and artificial intelligence, but they can raise the cost of running and sustain. Currently, operating drones such as these is difficult. In India, only a few farmers can afford to employ such high tech machinery to farm owing to financial constraints. The project is aimed at developing an affordable quad copter for farmers to use on their crops, with the goal of growing their output. We are developing core a framework with support of Raspberry Pi and OpenCV that can help predict crops yield with the help of inputs from numerous different sensor packages.

Design and Construction of a 0.75KVA Inverter Power Supply for Nigerian Homes and Offices

Over the years, there have been a gradual increase in the electricity generation capacity of Nigeria, with more gas power plants installed between 1999 2003 to augment power supply from the existing hydro and thermal power plants installed in the 1970s but despite gradual increase in Mega Watts MW of electric power generated, Nigerian electricity consumers continue to experience epileptic and unreliable power supply distribution. As at today, the power distribution companies referred to as the DISCOs supply epileptic or skeletal power to their customers which they termed 'load shading’. This term explains a situation whereby a power consumer or customer can obtain a power ration for some hours in the day and do not have power remaining hours in the day. Because of this, many consumers depend on generating sets as alternative source of power. This is inefficient and costly to maintain. Today it is possible to introduce the electric power inverter which converts battery DC voltage to AC voltage. Inside the inverter can be coupled an electric charging system which can charge the battery when there is power supply from utility power source. When this power source fails, the battery in turn supplies the inverter with DC which is being converted to A.C sometimes the inverter can also be connected to renewable energy source like solar, wind etc. These sources ensures an all round supply of DC for the inverter. Renewable energy can be particularly suitable for developing countries such as Nigeria where public power supply is totally unreliable. In response to the yearning of the majority of Nigerians for a steady power supply, this research paper tries to contribute in a little way by designing and constructing a 0.75KVA inverter to power homes and offices. The paper starts by defining what an inverter is, reviewed similar past works in literature, and it explained the principles of operation and components used with its circuit diagram. The completed work was tested and met its design specifications.

Thermo Hydraulic Performance of a Curved Solar Air Heater with Different Shaped down Turbulators using CFD

In contrast to the flat plate SAH design, curved designs of solar air heater ducts show substantial improvement in thermal characteristics, with the former showing a slight decrease in hydraulic efficiency. The creation of secondary vortices resulting in the mixing flow is demonstrated by curved SAH due to the centrifugal effect. In addition, the creation of dean vortices increases the rate of heat transfer in curved SAH. In flat plate SAH, these results are absent. In this present work, a three dimensional CFD analysis was carried out in a Curved duct of a solar air heater with a upper roughened wall with down configuration ribs having shape of half triangular, full triangular, and semi circular to investigate the heat transfer and flow behavior. The simulation programme ANSYS 17.0 was used for study of the heat transfer physiognomies of a curved duct of a solar air heater. The curved solar air heater with triangular rib roughness on the absorber plate has been found to yield improved results relative to the half triangular and semi circular rib and can thus be used to increase the heat transfer. The maximum enhancement in Nusselt number is found to be in triangular shaped ribs, which is 1.112 times that of half triangular corresponding to at a Reynolds number of 15,000 for the investigated range of parameters.

Examination of Performance of Seismically Isolated and Non Isolated RC Structure using Lead Elastic Bearing Isolators

In Reinforced Cement Concrete structures lateral loads are first which will grow proportionally with growth in floor height of the structure as a result of which lateral loads more effective in the top story in contrast to the bottom story due to which the structures are likely to react as cantilever and that forces develop high stresses, produce sway movement leads to serious damages and hence at last results in failure of the structure. Each of these causes form the study of the effect of lateral loads very dominant. Column is the most critical member in the building subjected to earthquake loading because failure of a column can affect the stability of the whole building. Column may fails due to lack of ductility, strength and weak beam column joint. A model of a 14 storey structure is made on ETABS Software and analysis of reinforced concrete framed structure under earthquake excitation has been carried using the linear static analysis methods as per the guidelines provided in IS1893 2016 codes to simulate seismic analysis. In order to study the effect seismic force on LRB system zone II of India a multi storey hotel building of G 13 of Square and L Shape configuration is taken in zone II with and without having a lead rubber bearing LRB at its base is analyses using linear static method. Supports has been removed at base and assigned as spring and different parameters like storey displacement, storey drift, base shear, and storey shear for all cases are evaluated and presented in the form of charts Based on results and comparing the parameters of different cases namely Asymmetric and Symmetric buildings with and without base isolation the conclusion can be made that Base isolation is very effective in reducing the storey drift in Symmetrical building and Asymmetrical building. For Asymmetrical building the base shear in X direction is reduced after the implementation of LRB system and in Y direction the same is reduced.

A Comprehensive Study on Social Network Mental Disorders Detection

The explosive development in prominence of social networking prompts the problematic usage. An expanding number of social network mental scatters SNMDs, for example, Cyber Relationship Addiction, Information Overload, and Net Compulsion, have been as of late noted. Side effects of this psychological issue are typically watched inactively today, bringing about deferred clinical mediation. In this work, we contend that mining on the web social conduct gives a chance to effectively distinguish SNMDs at a beginning time. It is trying to identify SNMDs in light of the fact that the psychological status cant be straightforwardly seen from online social action logs. Our methodology, new and inventive to the act of SNMD location, doesnt depend on self uncovering of those psychological variables by means of surveys in Psychology. Rather, we propose an AI structure, in particular, Social Network Mental Disorder Detection SNMDD that endeavors highlights removed from social network information to precisely recognize potential instances of SNMDs. We likewise abuse multi source learning in SNMDD and propose another SNMD based Tensor Model STM to improve the exactness. To build the versatility of STM, we further improve the effectiveness with execution ensure.

Diabetic Retinopathy Detection System from Retinal Images

Diabetes Mellitus is a disorder in metabolism of carbohydrates, and due to lack of the pancreatic hormone insulin sugars in the body are not oxidized to produce energy. Diabetic Retinopathy is a disorder of the retina resulting in impairment or vision loss. Improper blood sugar control is the main cause of diabetic retinopathy. That is the reason why early detection of retinopathy is crucial to prevent vision loss. Appearance of exudates, microaneurysms and hemorrhages are the early indications. In this study, we propose an algorithm for detection and classification of diabetic retinopathy. The proposed algorithm is based on the combination of various image processing techniques, which includes Contrast Limited Adaptive Histogram Equalization, Green channelization, Filtering and Thresholding. The objective measurements such as homogeneity, entropy, contrast, energy, dissimilarity, asm, correlation, mean and standard deviation are computed from processed images. These measurements are finally fed to Support Vector Machine and k Nearest Neighbors classifiers for classification and their results were analysed and compared.

Effect of Coconut Shell as a Coarse Aggregates on Behavior of Concrete

 The prices of building materials are rising day by day. The main ingredient of the concrete is coarse aggregate. Nowadays, many of the researchers are researching the material which can reduce the cost of construction as well as increase the cost. In developing countries, the possibility of using some agricultural wastes as well as industrial by products from different industries as construction materials will be highly desirable and has found to have several practical advantages. It was observed that the coconut shell has a great potential as a partial replacement of the aggregate in the concrete. The present work is only an accumulation of information about GFRGC and the research work which is already carried out by other researchers. Coarse aggregate were used in proportions of 5 , 10 , 15 to replace coarse aggregate in conventional concrete. The high demand for concrete in the construction using normal weight aggregates such as gravel and granite drastically reduces the natural stone deposits and this has damaged the environment there by causing ecological imbalance. This study aims in development the mix design of lightweight aggregate concrete using Coarse Shell as coarse aggregate together with cement and river sand. Coconut shell reinforced composites have been used as cheap and durable non structural elements.
