The relationship between the ratio of Ca to Si with shrinkage value was needed to be studied further.The strength of M-AAS was comparatively high, but the flexural strength was regressed in the long term. The compressive and flexural strengthes of 3 days were able to surpass 8MPa and 78MPa, respectively, and compressive strength of 90 days were all around 100MPa, but compared to flexural strength of 28 days, the flexural strength of 90 days was regressed by 19.0%. The high strength property of M-AAS associated with its hydration products and Interfacial Transition Zoo. The main hydration products of M-AAS were microcline and CSH, no calcium hydroxide was found. The coexistence of microcline and CSH worked as micro-aggregate by each other, and no weak ITZ, both resulted in its high strength. The regression of its strength was related to its high shrinkage property, because the crazing caused by shrinkage would decrease the strength, especially the flexural strength.

M-AAS强度较高，但长期抗折强度倒缩。3天抗折和抗压强度分别可超过8MPa和78MPa，90天抗压强度在100MPa左右，但90天抗折强度比28天抗折强度相比低19.0％。M-AAS的高强特性与其水化产物和界面过渡区有关，M-AAS的水化产物主要为微斜长石和CSH凝胶，没有氢氧化钙，微斜长石与CSH凝胶相互填充和配合共同起到强度的作用，M-AAS砂浆中几乎没有发现界面过渡薄弱区。M-AAS的强度倒缩现象与其收缩值较大有关，收缩会引起M-AAS硬化体内部出现微裂缝，使强度下降。
