Currently, this dross is processed in rotary kilns to recover the residual aluminium, and the resultant salt cake is sent to landfills. The present study investigates the utilization of recycled aluminium dross in producing concrete, which is suitable for hot weather concreting condition. The primary objectives of the experimental study are to examine the feasibility of using concrete blended with recycled aluminium dross under hot weather concreting situations and then to evaluate the strength and durability aspects of the produced concrete. From the experimental results it is observed that the initial setting time of the recycled aluminium dross concrete extended by about 30 minutes at 20% replacement level. This property of recycled aluminium dross concrete renders it to be suitable for hot weather concreting conditions. Based on the results obtained, the replacement of cement with 20% of Al dross yields superior mechanical and durability characteristics.

In the present study, river sand was partly replaced by the discarded foundry sand procured from steel moulding industries and the crushed brick masonry aggregate was used as coarse aggregate for the production of lightweight concrete. The experimental program involved casting of six distinct mixes with 0%, 20%, 40%, 60%, 80% & 100% replacement of fine aggregate by discarded foundry sand. The mechanical and durability properties of the lightweight concrete were assessed for each of the six diverse blends. Even though the 80% and 100% replacement mixes were found to be less dense than the rest of the mix, the blend of 40% replacement acquired desirable mechanical and durability properties when c...

Due to tremendous growth in the population, day to day, people are getting scanty water and its distribution also has become a challenging task. Water supply through pipelines is dominant among several water conveyance and distribution techniques. Water pipelines provide a solution to areas lacking a continual and sustainable water source. So in this connection, effective water distribution pipeline network is the need of the day. Water supply to the public should be uninterrupted in any situation, even after a severe earthquake. In this regard modeling the response of pipes to earthquake and some other shocks plays a vital role. In the present context, the seismic response of buried Hume pipe is modeled using finite element analysis. The study is concerned with simulation of the time period, frequency, joint displacement, joint acceleration of pipe, the lateral force that would occur due to seismic ground motion at the base of pipe structure and s...
