Inorganic Acid Resistance Performances of Magnesium Phosphate Cement: A Two-Year Observation.

Magnesium phosphate cement (MPC), a cementitious material that hardens through an acid-base reaction, is theoretically expected to exhibit strong acid resistance. However, studies on the durability of MPC in acidic environments remain limited. This study aims to systematically evaluate the acid resistance of MPC in common inorganic acid solutions across various pH levels.
