Abstract

332,925. Berry, H. April 30, 1929. Cements, Portland and Roman.-A cement is formed by heating calcium or magnesium oxide or hydroxide in an atmosphere containing sulphuric or sulphurous acid and grinding the resulting product with a base material such as waste slate, china clay, coal shale, sand. flint, or other mixtures of silica and alumina. The heat treatment in the acid atmosphere may be the primary calcination, for instance of the carbonate. or may be a secondary calcination, and is preferably carried out at a temperature of 700‹-900‹ C. and in the presence of steam. The products of a primary calcination may be dipped in a solution of sulphuric or sulphurous acid or their salts before being heated in the acid atmosphere, a preferred solution being aluminium sulphate acidified with sulphuric acid. Blast furnace slag may be regarded as a composition of base and binding materials, and may be used directly by calcining in an acid atmosphere.
