-3℃养护条件下矿物掺合料对 混凝土性能的影响
Effect of mineral admixtures on the properties of concrete under the-3℃curing condition
摘要
Abstract
The effects of mineral admixtures on compressive strength, chloride ion permeability and pore structure of concrete curing under-3℃ and standard curing condition were studied. The influence of mineral admixtures on the properties of concrete under the curing condition of-3℃ and standard curing condition was analyzed. The results show that: the strength of concrete curing under-3℃ in each age period is lower than that of the concrete curing under-3℃, which is not consistent with the growth of the strength of concrete under the standard curing condition. In the curing of-3℃, the chloride ion penetration resistance of concrete adding mineral admixtures is improved, and mineral admixtures at different ages can refine the pore structure of concrete, but the improvement effect is not significant compared with the standard curing condition.关键词
