Özet

The influence of styrene-butadiene rubber (SBR) latex on some physical and mechanical properties of concrete was investigated. The addition levels of SBR latex to the concrete mixtures were at ratios of 0%, 5% and 10% by weight of cement used. CEM I 42.5 R type cement with a content of 400 kg/m(3) and water to cement ratios of 0.40, 0.50 and 0.60 was used for all mixes. The change in the consistency, compressive strength, flexural strength, and water absorption by capillary on concrete was determined. The results obtained were compared with those of without SBR. Based on the results obtained, a comparable reduction in flexural as well as in compressive strength of polymer-modified concretes was observed. On the other hand, concretes included SBR indicated a significant improvement in the capillary sorption of concretes compared to those of without SBR.
