| 摘 要： | 碱土金属盐合成剂是一种新型水泥稳定土添加剂,其作用机理是通过水合作用与水泥形成交叉结构的晶体,进而提升水泥稳定土的强度和韧性水平。为研究碱土金属盐合成剂的实际改良效果,分别对加有碱土金属盐合成剂和无添加剂的水泥稳定土进行1d、3d、7d、14d、28d龄期时的无侧限抗压试验、抗拉试验、回弹模量试验。试验结果表明：水泥稳定土经改良后,其抗拉、抗压强度及回弹模量都得到了显著提升,弥补了水泥稳定土韧性较差、抗拉强度不足的缺陷。

| Abstract: | The alkaline-earth metal salt composition is a new type additive for cement stabilized soil,which forms the intersected structure crystals with the cement by hydration,so as to improve the strength and the toughness level of cement stabilized soil.In order to study the improvement effects of the alkaline-earth metal salts composition,two groups of the cement stabilized soils which contain the alkaline-earth metal salt composition or not are used.The unconfined compression tests,tensile tests,rebound modulus... |
