Abstract

PURPOSE:To obtain the titled compsn. having high viscosity, high fluidity and superior resistance to separation from materials by adding ethylhydroxyethylcellulose having a specified compsn., a nonionic defoaming agent aid a melamine sulfonate-based fluidizing agent to a concrete compsn. CONSTITUTION:Ethylhydroxyethylcellulose having about 1.5-2.5mol hydroxyethyl groups and about 0.5-1.5mol ethyl groups substd. in anhydrous glucose on the average and exhibiting 5000-30000cps viscosity when dissolved in water to 2% concn. is added to a concrete compsn. consisting of ordinary Portland cement, aggregate and water by an amt. so regulated that the viscosity of the water in the concrete compsn. is increased to 500-30000cps. A nonionic defoaming agent and a melamine sulfonate-based fluidizing agent are further added by 0.05-0.15pt.wt. and 0.5-2.5pts.wt. per 100pts.wt. cement, respectively, to obtain the titled compsn.
