Zusammenfassung: | 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.
Un proceso y composiciones para mejorar la resistencia de productos cementosos tales como concreto, argamasa, lechada, pavimento, bloques de pavimento, tuberia de concreto, bloques de concreto, concreto celular, concreto para techos extraido, concreto inyectado y concreto para estatuas a la penetracion de agua, que utiliza una cantidad menor de una sustancia de colofonia una sustancia cerosa en una cantidad en mayor de agua, para formar una mezcla sustancialmente acuosa utilizada como el ingrediente acuoso en la preparacion de un producto cementoso. La composicion de una emulsion acuosa de colofonia a una sustancia cerosa, agua, cemento y agregados, proporciona, ademas de mejorar la resistencia a la penetracion del agua, mantiene la resistencia del producto cementoso y puede proporcionar un vehiculo para agregar agentes que mejoran las propiedades el producto cementoso. |
