Abstract


In this research work presents the compressive strength of recycled aggregate concrete (RAC) with recycled coarse aggregate (RCA) that coming from single source and the results of an investigation on the influence of recycled coarse aggregate (RCA) on compressive strength of recycled concrete are accessible. Natural aggregates concrete cubes were cured in normal water for 28-days obtain virgin and RCA. The properties of natural coarse aggregate (NCA) and (RCA) and the compressive strength property a new concrete made from 60 and 100 percent of RA are analyzed with two cementious materials. The significant differences were observed between the property of compressive strength of original and RCA concrete and the results show the necessity of taking contaminations into account. The research studied to investigation of compressive strength result with partial replacement of cementious materials. In order to attain the compressive strength variants, 186-cube specimens with different recycled aggregate concrete (RCA) replacement percentages ratio of 60 and 100 percent with Ground Granulated Blast-furnace Slag (GGBS) and fly ash were tested below alike laboratory conditions. Data used in this study are collected from experimental works of us at RCC lab of Mugneeram Bangur Memorial (MBM) Engineering College Jodhpur. Along with data sets of conventional concrete, we have find out properties of GGBS and fly ash which used in concrete and selected the various data with different mix ID compressive strength experimental results compared with predicted Regration modal and results comes near to experimental. The research approved with the model using data exhibition consistent prediction of concrete strength at age of 28-days
