Abstract

the new Magnesium Phosphate Cement (MPC) was prepared by using the by-products of extracting lithium boron magnesium oxide (B-MgO ) as raw material. The influence of hydration hardening process was studied by testing setting time and compressive strength of different raw materials ratio of MPC. The phase composition and microstructure of hardening body morphology was analyzed by XRD and SEM. The result shows that there is a little impact of the distribution of raw materials ratio to the setting time, but the effect is remarkable to the compressive strength, phase content and microstructure of hardening body. By XRD and SEM observation, the best raw material proportioning of MPC has the highest generation of hydration products which from small petals of acicular crystals to rod and flat crystallization with a high degree of crystalline and compact structure and less defect.
