HYDRAULIC MATERIAL

摘要

PURPOSE:To prepare a hydraulic material having sufficient flowability and small in water to binder ratio by using a usual cement and accordingly capable of obtaining a hardened body extremely improved in workability and application property and excellent in strength and durability. CONSTITUTION:This hydraulic material contains at least cement and silica fume as the binder, a water soluble vinyl copolymer of <1wt.% based on the binder as a dispersing material and 60wt.% water based on the binder. This hydraulic material contains a granule made by flocculating the silica fume <=0.5mum in the particle diameter of the primary particle on the all or partial surface of the cement particle as a main material and a binder wherein the volume ratio of content of the particles having <=1mum particle diameters in these having 0.1-35mum particle diameters is <=10%.
