The present invention pertains to a phosphate cement composition and process for making such composition. More particularly, it pertains to a phosphate cement coating and process for making the coating for application to a given substrate.

The present disclosure provides a cementitious material and production method thereof. The method comprises steps of: (1) dry desulfurization and denitrification of a flue gas with a flue gas absorbent to give a by-product, wherein the flue gas absorbent comprises 10-23 parts by weight of a nano-sized metal oxide, 10-23 parts by weight of a micro-sized metal oxide, and 40-60 parts by weight of magnesium oxide, the nano-sized metal oxide being selected from one or more of the group consisting of SiO2, CaO, Fe2O3, Al2O3, CuO, V2O5 and MnO2, and the micro-sized metal oxide being selected from one or more of the group consisting of SiO2, CaO, Fe2O3, Al2O3, CuO, V2O5 and MnO2; and (2) uniformly mixing the by-product with magnesium oxide, an industrial solid waste and an additive to give the cementitious material.

A magnesium phosphate bone cement includes a powder agent and a liquid agent. A liquid-to-solid ratio of the liquid agent to the powder agent is 0.1-0.5 ml/g. The powder agent comprises following components: phosphate accounting for 32-70 wt %, magnesium oxide accounting for 28-65 wt %, and silicon-containing compound accounting for 1-15 wt %. Preferably, the powder agent further comprises ammonium dihydrogen phosphate, and degradable and adhesion-promoting material, wherein the ammonium dihydrogen phosphate accounts for 5-30 wt % of a total weight of the phosphate.
