Abstract: The present invention relates to an admixture capable of reducing viscosity of high viscosity concrete according to the increase of fly ash content up to 50% when manufacturing concrete. The present invention provides an admixture for high viscosity concrete wherein 20-40% of a polycarboxylic acid-based water reducing agent, 10-30% of a polycarboxylic acid-based maintaining agent, 0.5-2% of an antifoaming agent, 1-3% of a high dispersion agent and 10-25% of an air entraining agent are included in water, and thereby, overcoming the decrease of workability and production efficiency caused by the viscosity increase of concrete, as well as securing capabilities for stably generating and maintaining foams within ranges in which physical properties of concrete are not affected. Therefore, durability of concrete can be enhanced even when 50% or more fly ash is used. Accordingly, the admixture for high viscosity concrete of the present invention can increase the amount of fly ash used up to 50% on the basis of the weight of cement when manufacturing concrete, and therefore, can recycle resources and secure compressing strength and economic feasibility.

Abstract: The present invention relates to a concrete composition using blast furnace slag and manufacturing method thereof, and more particularly, to a concrete composition including cement, blast furnace slag, gravel, sand, water and hardening accelerator. The concrete composition using blast furnace slag according to the present invention uses a hydroxide ion group, silicates, a sulfur ion group and a nitric acid ion group as hardening accelerators so as to improve initial strength as initial condensation time is shortened by a hydration process after breaking impermeable film produced by the hydration process of the blast furnace slag through stimulation and provide a hardening property without additional production facility for remicon plants since the hardening accelerator is provided in powder. In addition, the initial strength is not deteriorated, an increase in unit water content is prevented and the physical property of cement is improved due to a simple mixing process of the blast furnace slag and cement.
