摘要: Abstract Phosphate cement-based binders were prepared by mixing MgO powder (M) with NH 4 H 2 PO (P) and borax (B). Effects of various factors including the amount retarder B, P/M ratio, fineness M, addition fly ash environment temperature on setting time mechanical properties magnesium phosphate binder (MPB) investigated. Results showed that early strength MPB mainly controlled temperature, but these had little influence final binder. It is interesting sets hardens within 1 h, even at −10 °C. A hardening mechanism proposed.
