Book excerpt: A latex used as an admixture in portland cement concrete or mortar is a water-emulsion organic polymer. This polymer emulsion will coalesce to form a continuous film within the matrix of the paste and around the aggregate, thus producing greater tensile and flexural strength and a more durable material (because it acts as a moisture barrier to the entry of liquid water but allows water vapor to migrate out). A literature search was conducted to collect information about latex admixtures and some minor laboratory testing was performed to corroborate some of the literature findings.
