Abstract

1,161,527. Cellular concrete. YTONG INTERNATIONAL A.B. 1 May, 1967 [5 May, 1966], No. 20023/67. Heading C1H. Aerated concrete is formed from hydraulic lime (defined) material containing a high percentage of silica acid, an aerating and/or foaming agent, and a readily water-soluble sulphate or sulphate-forming compound. H 2 SO 4 , (NH 4 ) 2 SO 4 , Na 2 SO 4 , K 2 SO 4 , and CuSO 4 are specified.
