掺土水泥

In this paper, mechanical properties of the sandy silt and fine sand mixed with cement and fly ashes in different amounts after different ages curing are researched, and the effect of cementing is compared. Through pull-out tests and direct shearing tests of geogrid in various soil, the interface characteristics of between geogrid and soil are measured.

本文通过室内物性试验、直剪试验和单轴压缩试验研究了采用不同掺量的水泥、粉煤灰加固后的砂质粉土和粉细砂养护不同龄期后的物理力学特性，并对加固效果进行了比较。

1Cement-soil samples with different stock-still time are compressed in strengthtest. It shows that if cement mixing content and clay content of reinforced soil aredifferent, the limited time to use cement-soil mixture will be discrepant.

本文重点研究了以下内容：(1)对不同静置时间的水泥土强度试验结果表明，随着水泥掺入比和被加固土的粘粒含量的差异，水泥土混合料的使用时间限制有所不同。

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。

The Yancheng lagoonal soft clays were used an original clay to form cement-mixed clays through mixing with powder cement or slurry cement and organic matters.

采用对盐城泻湖相软土掺入不同含量的有机质作为试料土，进行了大量的水泥加固室内试验。

The addition of 2%~6% water glass admixes to the slag cement-laterite, it is helpful to the short-term and long-term strength of the improved soil. The unconfined compression strength after curing 14 days can be increase to be 13.65 fold of original lateritic soil.

添加2%~6%水玻璃掺料於高炉水泥和红土混合土中，对其早期及晚期的强度皆有帮助，且龄期14天的无围压缩强度可达原状红土的13.65倍。

See parents should first soil and soot mixed together, get absorbed, and then in the middle of the small mounds of earth dug a pit, down in Sheung Shui; slowly to shovel coal ash and soil into the water and up until, and very uniform , as the cement spill it, be considered better.

见爸妈先把土和煤灰掺在一起，弄匀，然后在小土堆中间挖一个坑，倒上水；慢慢的把煤灰和土铲进水里和起来，直到和得很均匀，就像抹地的水泥那样，才算好了。

The addition of 20% fly ash admixtures to the slag cement-laterite, which have good development of strength.

添加20%飞灰掺料於高炉水泥和红土混合土中，对其强度的发展才有正面的效益。

ABSTRACT Mechanical properties of soil stabilized cement made from kiln ash, which consists of clinkers made from kiln ash only or the kiln ash with CaSO4-CaF2 compound mineralizer and certain amount of gypsum are studied. Moreover, the effects of burning temperature and gypsum content on the strength of the stabilized soil with kiln ash cement have been researched.

摘 要 研究了用纯窑灰、掺CaSO4-CaF2复合矿化剂的窑灰烧熟料与适量石膏混合配制的窑灰水泥稳定土的力学性能，并探讨了烧温度和石膏掺量对窑灰水泥稳定土强度的影响。

An elasto-plastic constitutive model which can simulate the strain softening and strain hardening is presented.

采用在原料土中掺入水泥的方法，人工制备大孔隙结构性土。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
