AERATED CEMENT MORTAR Russian patent published in 1997 - IPC

FIELD: constructional materials. SUBSTANCE: invention refers to construction of oil and gas wells and structures of non-autoclave cellular concretes for in-situ and small-piece building. Aerated cement mortar contains mineral binder, blowing agent, air, and water. When preparing cement mortar, two processes of pore formation proceed simultaneously: that involving natural and forced air entrainment and that involving gas former due to exchange reactions of carbonates. Dispensing of components provides homogeneous fine cellular structure of cement stone with improved strength characteristics. EFFECT: simplified preparation technique, spared time and reagent, no need in special equipment. 1 dwg , 1 tbl
