On the basis of this, from the view of material selection, mixture grade, cement dose, the usage of additive and maintenance management, some measures are put forward for preventing cement-stabilized subbase from shrinking cracking, and the targets of reducing the crack odds of subbase and the crack widths, or staying subbase from cracking are obtained.

在此基础上，从材料选择、混合料级配、水泥剂量、外加剂的使用、养护管理等角度提出水泥稳定粒料基层收缩裂缝防治措施，达到减少基层收缩开裂几率、减少裂缝宽度或延缓基层开裂的目的。

Using special alumine grog as aggregate and powder,adding active SiO2 fine powder and α-Al2O3 fine powder,using pure calcium aluminate cement as bonding agent,and adding effective additives,the prepared mixture was shaped by casting vibration,then a kind of lower cement and high alumina casting preformed block was made.

In this paper, the marine soft soil is mixed with 10% cement added with 0.5% NaOH and 0.5% Na2CO3 separately, which form two types of new cement-soils. Comparing with the undisturbed soil and the 20% cement-soil results in that the alkalescence additive can contribute to generate a large number of needle-like, rod-like or fibriform hydrate calcium silicate crystals. The hydrate calcium silicate crystals can inhibit the generation of calcic alum crystal which would bring expansive action. At the mean time, it can separate out hydrate calcium. The hydrate calcium silicate crystals and hydrate calcium constitute the filling and inclusions together among soil particles and on the surface of soil particles, which cut down the interstices of cement soil obviously. Therefore, the soil mass can be reinforced and the intensity can be improved.

现场试验中将海积软土与分别掺入0.5%NaOH和0.5%Na2CO3的10%水泥就地搅拌，形成两种新型水泥土，在与原状土及20%纯水泥土进行比较后，发现碱性外掺剂可以促使生成大量针状、棒状或纤维状水化硅酸钙晶体，抑制了能产生膨胀作用的钙矾石的生成，同时，有Ca2晶体析出，它们共同构成土颗粒间和土颗粒表面的充填物和包裹物，使水泥固化土的孔隙明显减小，密度和强度得到极大提高。
