ABSTRACT:
Dry cementitious compositions and methods for their application. The dry compositions do not have to be mixed with water but instead are poured, sprayed or troweled onto a substrate which contains a substantial excess of water than the necessary for the hydration of the materials. The dry cementitious material may be poured into water then applied to the substrate with no physical mixing other than that produced by pouring the cementitious composition into the water. The process also uses particles having similar drop rates and a cement content greater than 20% by wt.
