Effect of Styrene Butadiene Copolymer (SBR) admixture on high strength concrete

Currently, the concrete quality increases with improving technologies. High strength concrete (HSC) is a special kind of concrete produced in high fluidity by using chemical admixtures (plasticisers). In this study, for high strength concretes produced in C50/C60 designs, Styrene Butadiene Copolymer (SBR) in different weight ratios such as Control (0%), 1%, 3%, 5% and 8% was used instead of cement, and also strength properties of SBR were examined. For this aim, unit weight, water absorption ratio, compressive strength for 3, 7 and 28 days, splitting tensile strength, ultrasonic pulse velocity and frost resistance tests were applied. Also, SEM (Scanning Electron Microscope) and EDS analysis of samples were examined. As a result of the study, it is determined that concrete samples with 1% SBR admixture have higher values and contributions to strength.
