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。

For patients unfit for long revision procedures, and when the cement mantle is well preserved, especially in the peritrochanteric region, cement-in-cement revision to a longer stem, following adequate preparation of the old mantle to promote bonding between new and old cement, is possible.9 Unpublished data and personal communication with the Hip Unit of the Royal Devon and Exeter Hospital have provided us with encouraging results in this group of patients.

The results show that a proper air - entraining agent to be added not only can increase strength of cement polystyrene board effectively, but also decrease its density. The fly ash to be used instead of part of cement can save cement consumption and lower production cost under the prerequisite to ensure the property of cement polystyrene board.

结果表明：适量引气剂的加入不仅可有效提高水泥聚苯板强度，还可降低密度；采用粉煤灰代替部分水泥可以在基本保证水泥聚苯板性能的前提下，节省水泥用量，降低生产成本。

Theoretical analysis on three series of cements, i. e. Portland cement, high alumina cement and sulpho-aluminous cement, shows that alkalinity of the pore fluid of the balanced hydration product of sulpho-aluminous cement is the lowest, and its strength and alkalinity can be adjusted further by the adjustment of its components.

目前硅酸盐水泥、铝酸盐水泥、硫铝酸盐水泥等三大系列水泥的理论分析表明：硫铝酸盐水泥系列水化产物平衡时的液相碱度是最低的，且经过改性还可以进一步改善其强度和碱度等综合性能。
