摘要
A hydrated mineral charge is manufactured by grinding a composition selected from the group consisting of calcium aluminates, aluminous cements, and Portland cements, to a powder having an average fineness of from about 3,000 to about 5,000 square centimeters per gram (Blaine's specific surface), hydrating the composition with water to form a paste at a temperature from about 10 DEG C to about 100 DEG C, and adding a sufficient quantity of a liquefying surface active agent to the paste so that its viscosity is less than about 5,000 cps, and so that the paste has a solid content from about 60 percent to about 80 percent by weight.
