ABSTRACT:
Process for preparing dry fast-setting, magnesium phosphate cementitious composition capable of setting to a hardened mass at ambient temperatures following the addition of water thereto is disclosed. In this process unfiltered superphosphoric acid is added to a mixture of a magnesium-containing compound, e.g. MgO, and an aggregate, e.g. silica, with cooling to form a dry powder. This dry powder can be stored without caking, and forms a fast-setting cement having commercially acceptable compressive strength in the presence of water.
