Abstract
1450720 Pressing cementitious mix CALIFORNIA CEMENT SHAKE CO Inc 1 Nov 1973 [2 Nov 1972 6 Nov 1972] 17952/76 Divided out of 1450719 Heading B5A [Also in Divisions E1 and C1] A cementitious slab is made from a mixture of Portland cement, perlite, glass fibre, cellulose pulp, slaked lime, water and animal fat, by pressing the mixture to squeeze out the water. The animal fat comprises tallow, the cellulose is in the form of cardboard, and accelerators, colorants and air-entraining agents are added. Examples are given. A wedge-shaped slab is moulded as described in the parent Specification 1,450,719, which has an identical disclosure but claims the making of the wedgeshapes using vibration and pressure.
