HIGH FLUID CONCRETE AND CONCRETE SECONDARY PRODUCT

摘要

PROBLEM TO BE SOLVED: To create a recycling destination of molten slag grain while securing sufficient strength and homogeneity of a secondary product even mixing molten slag grain and preventing elution of harmful matter and reducing material cost. SOLUTION: High fluid concrete contains water of 160-190 kg/m3, binding material of 480-620 kg/m3, fine aggregate of 700-900 kg/m3, coarse aggregate of 700-900 kg/m3 and admixture of 4-8 kg/m3, and the slump blow value of which is >=65 cm or <=80 cm, and the binding material contains cement and micro powder of blast-furnace slag, and the fine aggregate contains sand and molten slag grain.
