Study on the Effects of Molar Ratio of MgO and MgCl₂ on the Properties of Magnesium Cement Straw Board Based on Experiment

Abstract:

Magnesium cement-based straw board is made of chloride-oxy-magnesium concrete as gel phase, a new building material with straw as reinforcing phase. The effects of molar ratio of MgO and MgCl₂on the static bending strength, softening coefficient and start time back to halogen moisture absorption of magnesium cement-based straw board are analyzed in detail. The result showed that,when n(MgO)/n(MgCl₂)=7(molar ratio),the mechanical properties and water resistance are the best, hydration products at this time is dominated by 518 phase.
