| 中文摘要: |
| 本文通过应用激发剂对含复合掺合料普通硅酸盐水泥体系进行改性，参照工程常用的混凝土配合比，设计配制了水泥砂浆及混凝土，并对水泥砂浆的力学性能及膨胀性能和混凝土力学性能的进行了研究。结果表明，激发剂对含复合掺合料普通硅酸盐水泥砂浆具有显著的增强减缩效果；对比工程常用C30混凝土配合比，能够明显降低C30混凝土中的水泥用量，增加复合掺合料的掺量，并提高混凝土的强度，这有利于商品混凝土企业的节能降本。 |
| 英文摘要: |
| In this paper, the general Portland cement system containing composite admixture was modified by applying activators. The cement mortar and concrete were designed and prepared according to the concrete mix ratio used in the project, and the cement mortar and concrete were designed and prepared, and the mechanical properties, expansion properties and mechanical properties of the cement mortar were studied. The results show that the activator has a significant enhancement and reduction effect on the ordinary Portland cement mortar containing composite admixture. The C30 concrete mix ratio used in the comparative engineering can significantly reduce the amount of cement in C30 concrete and increase the amount of composite admixture and improve the strength of concrete, which is conducive to the energy-saving cost reduction of commercial concrete enterprises. |
