Strengthening Mechanisms and Microstructure Evolution of Magnesium Potassium Phosphate Cement Modified by Nano-Fe2O3 and Nano-SiO2
Magnesium potassium phosphate cement (MKPC) exhibits rapid setting and high early strength, but its long-term performance is limited by microstructural heterogeneity and pore structure defects. These microstructural defects can increase pore connectivity and facilitate the ingress of aggressive agents, thereby limiting...
