Abstract
1345586 Cements DENKI KAGAKU KOGYO KK 21 April 1971 10493/71 Heading C1H A cement antishrinkage agent is obtained by burning in a high or low frequency induction furnace or a direct heating resistance furnace, a mixture containing CaO, Al 2 O 3 , Se 3 and F having a CaO/Al 2 O 3 wt. ratio of 0À5-20 to 1; 0À2-20% of an inorganic fluoride and 30-80% of CaSe 4 . The Al 2 O 3 can be generated in situ (from Al or AlN). The Al 2 O 3 and CaO are preferentially sized. The fusion can be cooled naturally, in an insulated container, by contact with water or an air blast. The agent is added to cement, Portland or rapid hardening, from which a concrete is prepared with sand and gravel.
