Improvements in porous or cellular cements and methods of making the same

Abstract

Abstract 263,571. Rice, J. A. Oct. 19, 1925. Porous concretes.-Cement, clay, and like products are rendered porous by adding to them when in the plastic state a foam obtained by agitating a solution containing a foam-producing agent and a foam-assisting agent. The foamproducing agent is a gelatinous material such as glue, albumen, or casein, or a glucoside- or saponin-containing substance. The foam-assisting agent is a natural or artificial resin, a resinate or resinic acid, a cellulose derivative, rubber, glycerol, or a phenol. Formalin may be added to either ingredient. A foam of increased stability results if made in the presence of chloroform vapour.
