Bonded aggregate composition and binders for the same

Abstract From the Canadian patent

Bonded aggregate compositions such as concrete concrete repair products, high , temperature refractories high temperature insulation and fire resistant insulation are made from an aqueous solution of phosphoric acid and a separate, storable dry mixture of suitable aggregate monocalcium phosphate, and calcium in the form of calcium aluminate cement or calcium oxide. The proportion of wet to dry constituents is variable so as to select the working time and strength of the aggregate composition typically on the order of ten , to fifteen minutes. The mixture of the preferred dry constituents and the , binder to be mixed with the aggregate to yield the preferred dry mixture are , also …
