| 1. | Admixtures should be avoided, particularly those that are added on site . 应当尽量避免使用掺和料,特别是避免使用须在施工现场掺加的掺合剂。 |
| 2. | Effect of mineral admixture on early age cracking of concrete 矿物掺和料对混凝土早期开裂的影响 |
| 3. | Hydration characteristics of cement kiln dust as cementitions materials 窑灰作为混凝土掺和料的水化特性 |
| 4. | Study on effect of fc admixture on strength improvment of ghpc 超细粉掺和料对高性能混凝土强度提高的影响 |
| 5. | At the same time , hpc can reduce the cement content per cube and use more mineral additives 同时,高性能混凝土可以利用大量的矿物掺和料取代水泥,减少单方混凝土水泥用量。 |
| 6. | The poor gas anti - permeability and carbonation resistance of recycled concrete can be offset by mineral additions 通过加入矿物掺和料,则再生混凝土的抗气渗性和抗碳化性能均可得到改善。 |
| 7. | With the addition of the mineral additives , the structure of the cement paste can be improved and the resistance of sulfate attacks can be advanced 掺入掺和料可以改善水泥浆体的结构,明显提高混凝土的抗硫酸盐侵蚀能力。 |
| 8. | Moreover , the autogenous shrinkage and the possibility of cracking in the early stage of the hpc also can be controlled , with the addition of the mineral additives 掺和料的加入还可以减小混凝土早期的自收缩,减少高性能混凝土早期开裂的几率。 |
| 9. | According to the code of durability test for normal concrete , the results show that the resistance of carbonate to the nonnal concrete is superior to the hpc 按照普通强度混凝土耐久性试验方法测得的不掺任何掺和料的混凝土抗加速抗碳化能力最好。 |
| 10. | The gas anti - permeability and carbonation resistance of recycled concrete , which was prepared by using waste concrete as recycled coarse aggregate ( rca ) and some cement and mineral additions as raw materials , were studied 摘要以废弃混凝土为再生粗集料,再适当掺加一定量的水泥和矿物掺和料,制成再生混凝土。 |
