BLAST FURNACE SLAG FINE PARTICLE COMPOSITION AND CEMENT COMPOSITION CONTAINING THE BLAST FURNACE SLAG FINE PARTICLE COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a blast furnace slag fine particle composition and a cement composition containing the blast furnace slag fine particle composition capable of resolving two problems that 1) compressive strength of initial material age and middle and long term material age is low and 2) a hydration reaction of the blast slag is decelerated and especially compressive strength of the middle and long term material age is reduced when it received high temperature history by hydration heat.SOLUTION: There is used a blast furnace slag fine particle composition obtained by adding an additive composition containing following 3 components of A to C, specific water soluble dextrin as an A component, specific polyalkylene glycol monoalkyl ether as a B component and one or two selected from ethylene glycol, diethylene glycol and glycerine as a C component at a specific ratio in a pulverization process of a blast slag and mixing and powdering.SELECTED DRAWING: None
