Experimental Study on the Behaviour of Concrete by Partially Replacement of Cement with Sugarcane Bagasse

We are well aware that the production of cement does a lot of harm to the environment. It includes tons of similar carbon emissions from other chemicals. Research has shown that every ton of cement output releases half a ton of carbon dioxide, so the need to regulate the use of cement is immediate. For example, Sugar Cane Bagasse Ash is hard to arrange on the hand materials squanders which is consequently ecological danger. The Bagasse debris gives concrete strong early cohesion, and also decreases cement porousness. During hydration, the silica present in the Bagasse debris reacts with concrete segments and gives extra properties such as chloride opposition, erosion obstruction and so on. Using Bagasse debris in concrete thus decreases the ecological pollution as well as improves the properties of cement and thus decreases the quality. This undertaking manages for the most part to substitute concrete with Bagasse debris in defined degree and to test the mixed cement on SCBA. The solid blend formed by fluctuating the Bagasse debris differential extent at 0 percent, 10 percent, 15 percent, 20 percent, 30 , 40 percent. The test result shows that the consistency of solid increases up to 10 per cent Sugar stick bagasse debris with concrete supplanting.

An Experimental Investigation on Incorporation of Fine Aggregate with Glass Powder and Cement with Zeolite to Mitigate Urban Heat Island Effect

An experimental study was done for replacement of glass powder and zeolite to evaluate the effect of urban heat island. All of the concrete sample mixtures carried out the intensified mortar bar test to evaluate the growth of the ASR. Perhaps this is partly related to a smaller glass particle size, the chemical characteristics of bottle as well as the participation of zeolite throughout concrete. Test specimens G20 Z10, GO Z10 and GI0 Z0, reached the power parameters. The G20 Z10 had the maximum resistance characteristics between them. These were found that intensity values with both the rising quantity of glass dust up to 20 per cent dose started to show a declining pattern. The replacing cement to zeolite powder research by up to 10 per cent indicates a tremendous pattern throughout strength properties. Decreased compressive tension, flexicurity and broken tensile strength may be due to reduced adhesion here between smoother surface of the glass particle as well as the cement. A G20 Z10 blend study revealed lower pavement surface temperature, which can also be considered a mitigating technique for urban heat islands.

A Research onto Study the Properties of Concrete with Partial Replacement of Aggregates by Plastic Aggregates

Plastic waste management is the main environmental issues in our country. The present study applies to the usage of recycled plastics as an alternative for aggregates in concrete. The motive of the study is to investigate the alteration in the physical qualities of concrete by the use of waste of plastics in concrete. The utilization of plastic aggregates was discovered to lead to the development of sturdy concrete. Additionally, with the plastics, the tensile and compressive strength of the concrete reduces. The foremost change brought approximately by using plastics is the fact that concrete’s thermal conductivity is decreased due to the utilization of plastics. It is able to thus be declared recycled plastics are usually utilized for thermal insulation of structures.Series of experiments had been performed in this current study for a comparison of the usage of Used Plastic as a replacement of sand in various different proportions. The main conclusions drawn was that the compressive strength increases with the inclusion of Used Plastic upto a certain proportions and then reduces the strength.

Damage and Loss Assessment of a Midrise RC Building in Downtown Area of Yangon Region

Yangon is an earthquake prone region and most of the low rise to mid rise residential reinforced concrete buildings are designed for gravity loads only. Therefore, evaluation of seismic vulnerability of buildings is essential in order to predict the probable damages and losses to this type of buildings. Damage assessment and earthquake loss estimation for gravity only design buildings should be performed to predict the damage probabilities and losses under the earthquake loading. In this study, seismic design and gravity design are accomplished for a five story residential RC building. Nonlinear static pushover analysis is performed using SAP 2000 software and capacity curves and fragility curves are developed for both designs. Damage probability matrices DPM are formed for design basic earthquake DBE level and maximum considered earthquake MCE level and the damage states are compared. The expected annual loss of the both designs are evaluated by means of the fragility curves and seismic hazard curve. Expected annual loss EAL values are also estimated and compared for both designs for 475 years and 2475 years periods.

Determination of Local Site Effects in Taikkyi Area, Yangon Region by using Microtremor Observations

Considering the possible local site effect is one of the most important facts in seismic hazard assessment. Depending on the local site condition, the characteristics of the seismic waves propagated through different geological layers and amplified the surface ground motion. In this study, one of the geophysical method of microtremor observations were carried out at 112 sites throughout the Taikkyi area. After analyzing the recorded microtremor observed data by Cygwin Software, we determined the horizontal to vertical spectral ratio HVRs that reflects the local site effects of the study area. The main outcomes of this research is to develop the fundamental frequency map and peak amplitude or soil amplification map of Taikkyi area. According to the evaluation results, the fundamental frequency is ranging from 1 to 2.3 Hz and most parts of Taikkyi area show in the range of 1.3 to 1.6 Hz. The peak amplitude of HVRs potential soil amplification is ranging from 1.5 to 3.6 and most parts of the area are in the range of 1.5 to 2.5.

Site Characterization and Seismic Site Response Study for Bagan Area

Bagan, the cultural heritage city of Myanmar located in the Mandalay region, which is very close to the active Sagaing fault. Most of Bagan’s cultural heritage monuments have been damaged due to earthquakes. Therefore, seismic response analysis is needed to evaluate site response characteristics for retrofitting and preservation of the historical monuments in Bagan. Site response studies require the characterization of subsurface materials considering local subsurface profiles of the site. The main target of the present study is site characterization and the estimation of seismic site response for the Bagan monument area. For this purpose, a geophysical survey such as microtremors was carried out to determine the variation of soil profile as well as the characteristics of the soil layers within the study site. Shear wave velocities at the study sites were estimated through the inversion of microtremors H V spectrum. The sites were categorized based on the average shear wave velocity of the overburden soil above the bedrock as Class ‘D’ Stiff Soil Profile and Class ‘C’ Very Dense Soil and Soft Rock . Equivalent linear site response analysis of layered soil deposits was carried out using DEEPSOIL software which determines peak ground acceleration PGA and response spectrum. The maximum surface PGA was found 0.24g and the maximum acceleration of surface motion is 1.13g at a period of 0.14s.

Modulation of Neural Cross Frequency Coupling analysis in VLSI Architecture

Cross frequency coupling CFC is a key mechanism in neuronal computation, communication, and learning in the brain. Abnormal CFC has been implicated in pathological brain states such as epilepsy and Parkinson’s disease. A reduction in excessive coupling has been shown ineffective neuromodulation treatments, suggesting that CFC may be a useful feedback measure in closed loop neural stimulation devices. However, processing latency limits the responsiveness of such systems. VLSI architecture is presented which implements the phase locking value of CFC to enable the application specific trade off between low latency and high accuracy processing.
