An experimental Comparison of admixtures used in recycling of concrete

In the construction field the need of coarse aggregate is high. On the same time many demolished concrete waste are used as land filling. To utilize the waste concrete by reclaim the coarse aggregate from the demolished concrete The aim of our project is to evaluate the use of recycled aggregate as normal coarse aggregate. In this project we are using only recycled aggregate. To increase the strength of recycled concrete by adding admixtures in recycled concrete . By studying the mechanical properties of concrete by replacing the cement with eggshell powder by 10%. The another admixture super plast 400 is added with 0.5% by the weight of cement. These admixture increase the strength of recycled concrete.
