Effects of metakaolin on a novel aerated magnesium phosphate cement with high early strength

Magnesium phosphate cement (MPC) was proved to be a cementitious material for preparing porous materials with high early-stage strength under standard curing condition. However, the poor water resistance of MPC-based porous materials limits the further application. This study employs metakaolin to improve the performance of aerated MPC. Testing results indicate that the presence of metakaolin produces more finer pores which makes the pore structure more homogeneous. For this reason, metakaolin improves both the compressive strength and water resistance with little negative impact on the thermal insulation property of aerated MPC. The metakaolin modified aerated MPC with a density of about 650?kg/m3 has 3-h strength of about 3?MPa and thermal conductivity of about 0.08?W/mK.
