Abstract

Binding agents are obtained by mixing at least 65 parts of anhydrite with at most 35 parts of another component selected from silicates and aluminates of Group IIA metals such as basic blast furnace slag or natural and/or artificial pozzolana. Fly-ash, 5-60 parts, may also be present. The anhydrite may be natural or synthetic or a mixture of both types. Other additions to the mixture are portland cement; an alkaline earth metal hydroxide e.g. lime; a hardening or setting agent, e.g. a hydrosulphate or a sulphate of iron potassium or zinc; and a water repellent, e.g. a silicone, an alkali metal or alkaline earth metal silicate, fluosilicate, phosphate, aluminate or stearate.
