Magnesium Phosphate Cement with Large Volume of Fly Ash

The accumulation of fly ash leads to severe problems in ecological environments. Various ways to excite the activity of fly ash in Portland cement based cementitious materials have been carried out for many years. In the present study, effect of large volume of fly ash in phosphate cement was studied. Dead burned magnesia, two phosphates (monoammonium phosphate and monosodium phosphate), and .

Magnesium Phosphate Cement| Concrete Construction Magazine

Magnesium Phosphate Cement. Such a cement is used in the same manner as portland cement, though the concrete requires less mixing water, hardens rapidly, requires no moist curing and can be put in service within about an hour at ordinary temperatures. It can also be used for making patches at such temperatures as 10 degrees F when necessary.
