“…The 518 phase is the main contribution of strength of chloride-oxy-magnesium concrete [8]. Matkovic used scanning electron microscope and electron microscope to observe the microstructure of hardening body of chloride-oxymagnesium concrete and found that 518 phase has good needle crystal or linear spiral tubular shape to make the hardening body density, high strength [9]. Therefore, chloride-oxy-magnesium concrete strength depends on 518 phase.…”

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.
