Research investigates SiO2 effects on magnesium phosphate cement performance, suggesting optimization strategies.

This research aims to understand how SiO2 impacts the performance of magnesium phosphate cement through chemical and physical mechanisms.
Prepared MgO-SiO2 clinkers with SiO2 additions of 1% to 9% and calcined at 1100 °C to 1500 °C.
Conducted XRD-Rietveld refinement to assess phase composition and crystallinity.
Evaluated workability, compressive strength, and hydration heat analyses.
Analyzed the relationship between SiO2 dosage and mechanical performance.
SiO2 decreased reactive MgO content by forming forsterite, lowering compressive strength.
Optimal calcination temperature for strength was 1200 °C, with 9% SiO2 reducing strength by ~40%.
Increased SiO2 enhanced heat flow rate and cumulative heat release, but did not improve strength.
Mg2SiO4 formation increased with SiO2 dosage and temperature, supporting evidence of dual damage.
