The water-reduction and water-retention of styrene-butadiene rubber (SBR) latex in mortar and the influence of the latex on the physical properties of mortar at a certain water-cement ratio (mw/mc) of 0.4 or flow (170+or-5) mm were investigated. Two curing methods (wet curing and mixed curing) were evaluated. The results show that the SBR latex has the effect of the water-reduction and water-retention in mortar. The water-reduction rate increases to about 50% when the SBR latex-cement ratio (mp/mc) increases up to 13%. The water-retention rate reaches 99% when the mp/mc is 7% at a constant flow. With a constant mw/mc, the bulk density of the SBR latex-modified mortars decreases to a minimum at the mp/mc of 10%, and its porosity and the mean pore diameter change contrarily. However, the effect of the mp/mc on the bulk density, porosity and pore diameter is insignificant at a constant flow of (170+or-5) mm. The porosity and the pore diameter of wet-cured SBR latex-modified mortars are lower than those of mixed-cured ones. The capillary water adsorption of mortar is bated effectively by the addition of the SBR latex.
