ADMIXTURE COMPOSITE FOR CEMENT ALTERNATIVE, CEMENT BINDER COMPOSITE AND CONCRETE COMPOSITE USING THE SAME

摘要

PURPOSE: An echo admixture composition, a cement binder composition including thereof, and a low carbon concrete composition are provided to offer the function similar to cement at the low temperature, using blast furnace slag micro powder. CONSTITUTION: An echo admixture composition for using instead of cement contains the following: 55~70wt% of blast furnace slag micro powder with the fineness of 4,000~6,000cm^2/g; 2~5wt %of Na_2SO_4 powder as an alkali activator; and 25~40wt %of limestone highly pulverized powder with the fineness of 6,000~12,000cm^2/g. A cement binder composition is formed by using the echo admixture composition instead of cement.
