Nano Manufacturing An Introduction

Nanotechnology involves the manipulation of matter in atomic and molecular scale. It is emerging as a principal discipline that is integrating chemistry and materials science. It holds the promise of being a main driver of technology with significant impact for all aspects of society. Nano manufacturing is manufacturing at the nanoscale. It is an interdisciplinary field covering physics, chemistry, biology, materials science, and engineering. This paper provides an introduction to nano manufacturing.

Study on Properties of Concrete using Rice Husk Ash and Fly Ash as a Partial Replacement of Fine Aggregate and Cement with Sisal Fiber

Concrete is the most widely used construction material in the world it is a mixture of cement, sand , coarse aggregate and water.Storage and safe disposal of industrial by product such as fly ash, SF and rice husk ash is a huge problem everywhere, reuse of these waste eliminates reduce the problem.In this experiment fine aggregate is replaced 0 ,10 ,20 ,30 and 40 of its weight by rice husk ash and cement is replaced 20 of its weight by fly ash and SF in all concrete mix and there effects are studied.In this experiment the compressive strength of the concrete is increased. It is found that the strength increases with the replacement of cement and fine aggregate by fly ash at about 19 , SF at 1 and RHS at about 40 , and beyond this the workability of concrete will not achieved.

BIM Competencies for Minimizing the Construction Remnant of Project Moving Forward from Linear to Circular Economy

A modern lifestyle, alongside the advancement of technology has led to an increase in the type of waste and its amount and being generated, leading to a waste disposal catastrophe. Therefore in the past decades, construction and demolition CandD waste issues have received increasing attention from both practitioners and as well as from researchers around the world. An affordable waste management action to reduce waste at all phases of design and construction with special consideration to the long term environmental and economic impacts of continuous waste generation. Therefore, many studies on coherent CandD waste minimization and management have been conducted. Although 21 process related and 8 technology related limitations in CandD waste management and minimization have not yet been resolved. Building information modeling BIM helps project participants improve the processes involved and technologies in the planning, design, construction, and demolition phases, thereby managing and minimizing CandD waste efficiently. Therefore, this paper identifies for coherent CandD waste management and minimization, such as phase planning, site utilization planning, 3D coordination, design review, quantity take off, construction system design, digital fabrication, and 3D control and planning BIM has the potential opportunities. The BIM based approaches would CandD waste management and minimization processes and technologies by addressing existing limitations through in depth literature review.

Practical Skills Expected of Block Brick Laying and Concreting Students in Technical Colleges in Rivers State

The study identified the practical skills expected of block laying, brick laying and concreting students in technical colleges in Rivers State, Nigeria. The population of the study consisted of 80 respondents, comprising of 70 registered builders from the ministry of works and housing and 10 block laying, brick laying and concreting teachers of the three National Board for Technical Education NBTE accredited technical colleges in Rivers State offering the course. To guide the research, a question was developed and a hypothesis was formulated. An instrument was developed and validated by experts subsequently it was used by the researchers to obtain information from the respondents. Mean and the standard deviation were used to analyse the research question, while t test was used to test the hypothesis at 0.05 level of significance. Findings revealed a 44 item practical skills list expected of students of block laying, brick laying and concreting in technical colleges in Rivers State. It was also found that there is no significant difference in the mean response of technical teachers and registered builders in block laying, brick laying and concreting. Regular field trips to construction sites, acquisition of modern machines and equipment, deepened collaboration with private construction firms for enhanced trained of students were recommended.

Planning and Scheduling Construction Projects using Primavera Software A Case Study

Planning and Scheduling are very essential in the large infrastructure projects like road and bridge construction. These projects have numerous stakeholders and large amount of money, resources are invested. Improper planning and scheduling leads to loss of resources, increase in project cost and unpleasant delays. But with computer and software evolution, it is now possible to plan these projects using software like Primavera P6 and Microsoft office project. This paper deals with presentation of AwasYojna project in New Market Bhopal comparing the two different blocks namely Block A and Block B. The project framed stated the advantage and added benefits of web based primavera P6 for planning and scheduling of structures under construction under the government scheme of “AwasYojna” framing the issues and complications faced in the time frame of construction and availability of resources.

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.
