摘要
研究了不同水胶比、不同矿物质粉体掺量的砂浆和混凝土 ,经标准养护至 5 6天、 90天时的导电量。在相同水胶比和相同矿物质粉体掺量下 ,混凝土的导电量远低于砂浆的导电量。含矿物质粉体的砂浆及混凝土的导电量均低于基准砂浆及混凝土的导电量。导电量随水胶比的降低而降低 。
In this paper, the effect of mineral powder and W/B ratio on the charge passed with mortar and concrete under 56 day and 90 day's standard curing age is investigated. For the same W/B ratio and same content of mineral admixture, the charge passed through concrete is far lower than that through the mortar. The charge passed data of either mortar or concrete with mineral admixture are lower than that of the plain samples. The charge passed of mortar and concrete decreases with the decrease of W/B and increase of curing age. [
