ABSTRACT:
A cementitious mixture includes hydraulic cement, fly ash, and an effective amount of unfired nature finely divided material, such as a clay, containing at least about 35% alumina, to accelerate the early strength of a mix. A method of accelerating early strength in a cementitious mix comprises the adding of alumina in the form of an unfired raw material, such as clay, in an effective amount in such mix.
