摘要
A process and compositions for improving the resistance of cementitious products such as concrete, mortar, grout, paving, paving blocks, concrete pipe, concrete blocks, cellular concrete, extruded roof concrete, shot crete and concrete statuary to the penetration of water utilizes a minor amount of aqueous emulsion of rosin or a waxy substance in a major amount of water to form a substantially aqueous mixture utilized as the aqueous ingredient in the preparation of the cementitious product. The composition of an aqueous emulsion of rosin or a waxy substance, water, cement and aggregate provides, in addition to improved resistance to the penetration of water, maintains the strength of the cementitious product and can provide a vehicle for adding property enhancing agents to the cementitious product.
