| 1. | Study on model of micro - pores construction of cement - stone 水泥石孔隙结构模型的研究 |
| 2. | Evaluation procedure for high temperature property of set oilwell cement 油井水泥石抗高温性能评价方法 |
| 3. | Reduction in friability of well cement stone and its function mechanism 油井水泥石脆性降低的途径及其作用机理 |
| 4. | A study of pore specific surface area and its correlation with the strength of silica fume cement paste 硅粉水泥石中的孔比表面积及其与强度的相关性 |
| 5. | Mathematical model for structure and compressive strength of hardened class g oilwell cement paste at low temperature 低温下油井水泥石孔结构与抗压强度的关系 |
| 6. | Influences of caustic - resisting glass fiber to mechanical properties of set oil well cement blended with mineral slag 耐碱玻璃纤维对掺矿渣油井水泥石力学性能的影响 |
| 7. | The addition of calcined kaolin to cement increased the chemical shrinkage of cement stone , but it had no distinct impact on the self - shrinkage of cement stone 煅烧高岭土掺入水泥中,增加了水泥石的化学收缩,对水泥石的自收缩的影响并不明显。 |
| 8. | According to the reinforcement mechanism , some experimental phenomena and rules in the strength tests of cemented soil and cemented stone are explained 根据固化机理,解释了水泥土和水泥石强度试验中的一些现象和规律,分析了纳米硅粉改性水泥土的适用性。 |
| 9. | It may be the deposition of caco3 in capillary that divide the large capillary into small one . carbonation can also lower the water permeability of samples 因此碳化将会降低水泥石和水泥砂浆的渗透性,渗透性的降低与水灰比有关,水灰比越大其降低的幅度也越大。 |
| 10. | Their effects on the chemical shrinkage , self - shrinkage , hole structure of cement stone and on the shrinkage of mortar and concrete were also studied thoroughly , and a concrete admixture with high performance of crack - resistant and water - repellent was prepared 通过它们对水泥石的化学收缩和自收缩、孔结构以及对砂浆及混凝土的收缩性能的深入研究配制出了一种性能优良的混凝土抗裂防水外加剂。 |
