Abstract

Construction work has increased rapidly from the past two decades. With these construction activities going up, we find lacking of the construction materials, particularly aggregates. So, finding an alternate resource and their feasibility; study is the need of our project. Recycled or used aggregate proves to be a good alternative here. Therefore, the investigation was carried out using compressive strength test, confined to the objective we have tested and empirically observed no. of M20 grade concrete cubes in stipulated time frame for different proportions of recycled aggregate i.e. 0, 10, 20, 30, 40 and 50% as replacements with new aggregate and finally as per results found that 20% recycled aggregate serves our purpose on reliable strength basis for most of the feasible construction works while confirming the optimum utilization of the waste aggregate. The samples were cured for specified periods and tested in the laboratory for compressive strength. The result was carried out by using crushing strength, water absorption test, impact test, bulk density etc. There were total of six batches of concrete mixes, consisting of every 10% increment of recycled aggregate replacement from 0 to 50%. Here, we take a constant water cement ratio of 0.5.
