Abstract
Magnesium phosphate cement binder systems and method for providing magnesium phosphate cements are described. In an embodiment, a magnesium phosphate cement binder system may include magnesium oxide that has been calcined at a temperature of between about 900° F. to about 1800° F. The magnesium phosphate cement binder system may also include a phosphate material. Other formulations, compositions, and methods are also described.
Claims13
A magnesium phosphate cement composition comprising:
- magnesium oxide calcined to exhibit a caustic magnesia activity neutralization time of between about 9 second to about 30 seconds using a 1.0N acetic acid and a magnesium oxide content of between about 10% to about 100%, wherein the calcined magnesium oxide includes a surface area in the range of between about 10 m2/g to about 120 m2/g;
- and
- a phosphate material.
