Basic Properties and Carbonation of Concrete with Partial Replacement of Cement by Rubber Latex and Limestone Powder
Keywords:Basic properties, Mechanical properties, Carbonation depth, Rubber latex, limestone powder
This research aims to study the basic properties, mechanical properties and durability of concrete with partial replacement of cement by rubber latex and limestone powder in ordinary Portland cement (OPC). The investigation included basic properties were normal consistency and setting time of paste. The mechanical properties studied were compressive strength, slump and porosity of concrete and the durability property tested was carbonation of concrete. Concrete with the replacements of rubber latex in OPC by weight was 0.5, 1 and 1.5%, and replacements of limestone powder in OPC by weight were 5, 10 and 15%. The water to binder ratio was 0.55. The results showed that the water requirement of paste with rubber latex and limestone powder was higher than that of OPC paste. Additionally, the setting time of paste with rubber latex was higher than that of OPC paste, while paste with limestone powder was lesser when compared to that of OPC paste. The slump of concrete with rubber latex and limestone powder was lesser than that of OPC concrete. Moreover, it was found that a partial replacement of cement with an optimum content of rubber latex and limestone powder makes mechanical properties including better durability properties.
