5The failure strains of cement-soil are calculated, and initial tangent modulusand average deformation modulus of cement-soil with same cement mixing content arecalculated. Then fit them with strength. The relation between ultimate deformationmodulus and strength, cement-soil of same curing period, is fitted too. The conclusionis that deformation modulus of cement-soil with some stock-still time are close to thesewhich compacted without stock-still time.

5计算分析了水泥土的破坏应变；计算了相同水泥掺入比水泥土的初始切线模量和平均变形模量，将它们与抗压强度的关系进行拟合，将同龄期水泥土的极限变形模量与抗压强度进行拟合，结果表明，一定静置时间的水泥土的变形模量与t=0h的水泥土的变形模量相差不大。

Micronucleus test results exhibited that significant differences in micronuclear rates were determined between 0.4 mL bone cement and 0.4 mL microsphere-coated bone cement groups and negative control group, but no significant difference was detected among other groups. This revealed that this microsphere-coated bone cement leaching liquor did not show significant cell heredity toxic effects. Nevertheless, microsphere-coated bone cement in the high concentration and high dosage groups exhibited low toxic effects, mainly showing increased hemolysis rate and micronuclear rate. Thus, it was necessary to control the dosage and concentration of microsphere-coated bone cement.

微核实验结果显示除0.4 mL骨水泥组和0.4 mL微球骨水泥组的微核率与阴性对照组差异有显著性意义，其余各组差异无显著性意义，说明该微球骨水泥的浸提液无明显细胞遗传毒性作用，但是高浓度和高剂量组的微球骨水泥仍有较低的毒性作用，主要表现为溶血率和微核率的提高，因此在应用时要适当控制微球骨水泥的剂量和浓度。

It is also revealed that the refractoriness of Portland cement and alumina cement are actually at the identical level, and refractoriness of castable with low cement content of Portland cement, substitution of alumina cement, will not cause worsening of refractoriness.
