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.
