Abstract
Magnesia-phosphate cement (MPB) was prepared by mixing MgO powder (M) with NH4H2PO4 powder (P) and Na2B4O7. 10H(2)O powder (B). In field applications, MPB mortar is usually used for rapid repair. Effects of many parameters, s uch as sand/MPB ratio, water/MPB (W/MPB) ratio, kind of sand, fly ash repla cement of MPB, specimen volume, temperature and moisture on mechanical prop erties, and fluidity of MPB mortar were investigated in this paper Some sys tematic information on the various field applications of MPB mortar was als o discussed.
