Abstract
A method of reducing the water requirements of a cementitious slurry and of improving the properties of a cementitious slurry by adding a mineral additive comprising fly ash having a predominant particle size of up to about 10 microns, and/or aluminous material having a predominant particle size of up to about 150 microns. The additive acts as a water reduction agent and can replace either wholly or partially a conventional plasticiser.
