Effect of water-based acrylic copolymer on void systems of cementitious repair mortar

Abstract Recent literature has found excessive air content as a drawback in the polymer-modified cement mortars. Excessive air content has an adverse impact on the compressive strength of polymer-modified, cement-based mortars. Entrapped air voids in the cement based mortars are typically classified greater than 1 mm in diameter. In contrast to these voids, the entrained air voids (
