Influences of Polymer Fiber and Polymer Latex on Physical Properties of Cement Mortar

Article Preview

Abstract:

Two kinds of polymer fiber and polymer latex are used to improve the toughness and bondability of cement mortar. The influences of the fiber and latex on the compressive and flexural strength, compressive strength-flexural strength ratio (CS/FS), bond flexural strength and compactedness of the hardened mortar were studied. The results showed that both of the latex and fibre can improve the compressive and flexural strength of mortar in low content, decrease the CS/FS, and then improve the toughness significantly. The bond flexural strength of mortar can be improved by 40-50% when the latex is added. The effect of fibre-latex added together was better than that of two matters added separately. The optimized components for Fibre-Latex hybrid were: 0.28% of PVA+5% of ACE.
