Performance of Cement Mix Plus and Styrene Butadiene Rubber Polymers in slag Based Concrete

In recent times, the construction sectors are using the polymers to enhance the strength of cement concrete and cement mortar. This paper presents a study on the effect of polymers (cement mix plus and styrene butadiene rubber) on the strength of concrete. The concrete was manufactured with cement and slag as partial replacement of cement at 50% and 70%. Cement mix plus and styrene butadiene rubber (latex plus) polymers were mixed individually at 1%, 3% and 5% by mass of cementitious material (Cement + Slag). The mechanical properties such as slump, dry density and compressive strength of cement polymer concrete and slag polymer concrete are compared. The slump of cement polymer concrete was 50% and 75% higher than 50% & 70% slag polymer concrete with cement mix plus at 1% respectively. It was also 36.67% and 70% higher than 50% & 70% slag polymer concrete with latex plus at 1%. The dry density of 70% slag polymer concrete was higher than 50% slag polymer concrete and cement polymer concrete with both the polymers. The 28 days compressive strength of 50% slag polymer concrete was 25.06% and 40.99% higher than cement polymer concrete and 70% slag polymer concrete with cement mix plus at 5% respectively. It was also observed that the compressive strength of 70% slag polymer concrete was 17.99% and 22.49% higher than cement polymer concrete and 50% slag polymer concrete with latex plus at 1% respectively.
