ADMIXTURE COMPOSITE FOR STRENGTH IMPROVEMENT OF READY-MIXED CONCRETE AND CONCRETE PRODUCTION METHOD USING THE SAME

摘要

The present invention relates to a three-component mixture composition composed mainly of blast furnace slag fine powder, calcium sulfoaluminate, and sulfate salts to be usable as strength enhancers for ready-mixed concrete mixtures, and a ready-mixed concrete production method using the mixed material composition.;Strength enhancing mixture composition for ready-mixed concrete mixed material according to the present invention, blast furnace slag fine powder 55 to 95% by weight; Calcium sulfoaluminate 2-10% by weight; And, the sulfate is 3 to 35% by weight; characterized by consisting of. At this time, the blast furnace slag fine powder is adopted to have a powder degree of 6,000 ~ 12,000 cm 2 / g, the sulfate is coal manganese (Na ₂ Ca (SO ₄ ) ₂ ) is adopted.;The method for producing ready-mixed concrete according to the present invention stores the above-mentioned three-component ready-mixed strength increasing mixture composition in one silo and then puts it in the ready-mixer mixer to produce concrete. It is characterized by a compound design that occupies ~ 25% by weight.;Concrete, Strengthening, Blast Furnace Slag, Calcium Sulfo Aluminate, Sulfate, Ready Mixed Concrete, Ready Mix
