Abstract

PURPOSE:To cheaply manufacture the hydraulic setting composite material, by admixing respective limited amount of the water granulated slag of the specified particle size being prepared from the blast furnace slag by crushing,and by pressing (thread rolling) the mixture alone or after being added with the coarse aggregate, so as to cause the hydration setting. CONSTITUTION:The unaged converter slag is crushed to obtain the slag of the particle size under 10mm; this slag 20-60wt parts, the water granulated blast furnace slag 30-70 parts, and the recovered gypsum from the exhaust gas desulfurization, etc., 5-15 parts, are mixed together with. Next, this hydraulic setting composite material alone or after being added with the coarse aggregate, containing 5-15% moisture, is pressed (thread rolled) for causing the hydration setting. This product is used for the roadbed material, the railway roadbed material, the blacktop, the improvement of the soft soil, etc.
