Modelling and Optimizing the Durability Performance of Self Consolidating Concrete Incorporating Crumb Rubber and Calcium Carbide Residue Using Response Surface Methodology

The world is now focusing on a sustainable environment and reducing the effects of global warming. One way to achieve such targets properly utilize waste reduce greenhouse CO2 emissions. cement industry responsible for almost 10% emission due high demand in construction industry. ways minimize this effect partial replacement by other materials concrete. Therefore, study, calcium carbide residue (CCR), which highly rich oxide, partially replaced management. Waste tires were grinded fine sizes crumb rubber (CR) aggregate. paper investigared influence CR CCR durability properties heat/temperature resistance self-compacting concrete (SCC). experiment was designed using response surface methodology investigate SCC properties, design models SCC, optimize mixes best results. considered acid attack (H2SO4 attack), salt (MgSO4 water absorption. heat weight reduction residual compressive strength after heating samples at 200 °C 400 °C. results findings showed that negatively affect SCC. Furthermore, affects while slightly improved it developed RSM significant with degrees correlation predictability. optimum achieved 2.9% as aggregate 5.5% replacement. can predict performance terms elevated temperatures CR, CCR, fly ash variables. This will need carrying out experimental work, thereby cost time.
