Impermeability of Wet-Sieving Fine Aggregate Concrete Made from Ordinary Concrete
The research is part of wet-sieving concrete technique for building thermal insulated reinforced concrete composite wall. The fine aggregate concrete is made from ordinary concrete passing sieve with square mash of 15 mm for casting surface concrete layer of the wall, the recomposed concrete is made of residual concrete stayed on sieve and ordinary concrete for casting reinforced concrete structural wall. The impermeability of fine aggregate concrete and recomposed concrete are measured by water permeation method and chloride-ion permeation method, the relative permeability and chloride-ion diffusion coefficients of concrete are determined. Based on the test, the effects of the changes of aggregate series, sand ratio and cement paste on the impermeability of concrete are analyzed.
