Evaluation of the Impact Resistance of Hardened Cement Pastes by Adding Styrene-Butadiene Rubber Latex

다국어 초록 (Multilingual Abstract)

In this article, the effect of latex polymer modification on improving the impact resistance of cement pastes has been investigated.
The control cement mixture was proposed with water-cement ratio of 0.5. Based on that, the cement pastes were modified by partially substituting water content with Styrene-Butadiene Rubber (SBR) latex. The mixture ratios were prepared by adjusting the various SBR latex dosages from 5 wt % to 20 wt % of water content. The specimens of modified pastes in the hardened state were tested by Charpy impact experiment and compared to the pure ones after 7, 14, 28, 45, and 60 days of curing. The observation results showed that there is a remarkable improvement in the impact resistance of modified cement pastes. Further, the optimal SBR latex dosage of 10% was proposed.
