ABSTRACT:
A dry blend capable of forming a fast-setting cement when reacted with an aqueous component. The blend comprises: a solid phosphorus pentoxide (P.sub.2 O.sub.5) containing component; a solid component comprising a magnesium containing compound; and an optional aggregate.
The solid P.sub.2 O.sub.5 containing component is preferably spent solid phosphoric acid catalyst.
The dry blend remains a free flowing powder until contacted with the aqueous component, preferably water, then a reaction occurs forming a fast-setting cement.
