Abstract:This paper deals with the effects of silica fume content and polymer-binder ratio on the properties of ultrarapidhardeningpolymer-modified mortar using silica fume and ethylene-vinyl acetate redispersible polymer powder instead of styrenebutadienerubber latex to shorten the hardening time. The ultrarapid-hardening polymer-modified mortar was prepared with varioussilica fume contents and polymer-binder ratios, and tested flexural strength, compressive strength, water absorption, carbonationdepth and chloride ion penetration depth. As results, the flexural, compressive and adhesion strengths of the ultrarapid-hardeningpolymer-modified mortar tended to increase as increasing polymer-binder ratio, and reached the maximums at 4 % of silica fumecontent. The water absorption, carbonation and chloride ion penetration resistance were improved according to silica fume contentand polymer-binder ratio.
