Utilization of styrene-butadiene rubber (SBR) polymer replacement of fine aggregate in concrete

Abstract
This paper aims to examine the effect of styrene-butadiene rubber (SBR) polymer incorporation on the performance of no-fine aggregates produced from lightweight concrete. This type of concrete usually utilized for partitions and external walls and infilling panels in framed structures. Three concrete mixtures with varying aggregate/cement ratios (4:1, 6:1, and 8:1) were used by volume. Each of these mixtures consists of five sub-mixes with different proportions of polymer/cement (0, 5, 10, 15, and 20%) by mass. For using a (300×50) cylinder specimen, a tensile strength test was carried out on all concrete mixes after curing on 28 days in water. The test results demonstrated that no-fine aggregate concrete\'s strength increased with the increase in the polymer/cement ratio for all mixes. Whereas the rate of development in a group ratio (4:1) for water curing when increasing the polymer (0-10) %, was (192) % more than the strength in the control mix and the mix (M4-15) for water curing the strength was (130) % more than control mix. That indicates that the polymer is more effective in poor mixtures due to its containing high voids.
