混凝土是水泥基多元复合材料,在配制混凝土时,诸元之间的增减、比例,对混凝土各种性能的影响,存在着一定的内在规律性,如水灰比与强度的规律,以及散见于其他文献中的骨灰比、包盖系数等的论述。在混凝土技术发展到向高强、高性能、大流动性泵送施工方向发展的今天,有必要对混凝土配合比中诸元之间的配合与混凝土施工性、强度及长期性能之间关系的规律性进行探讨。
Concrete is a cement-based multi-component composite material, in the preparation of concrete, the increase and decrease between the yuan, the ratio of various properties of concrete, there are some inherent laws, such as water-cement ratio and strength of the law, Other references in the ashes ratio, coverage coefficient and so on. In the development of concrete technology to the high-strength, high-performance, high-mobility pumping direction of the development of construction today, it is necessary to concrete mix ratio between elements and the concrete construction, strength and long-term performance of the relationship between the regularity To explore.
