HIGH STRENGTH CONCRETE BINDER COMPOSITION FOR STEAM CURING

摘要

The present invention relates to a binder that is used for binding of component elements in a concrete secondary product. The present invention provides a high-strength concrete binder composition for steam curing that allows a strength which is required for the concrete secondary product to be achieved through room-temperature curing and steam curing processes alone without autoclave curing, the composition including 45 to 50 parts by weight of blast furnace slag powder, 3 to 8 parts by weight of reducing slag powder, 25 to 27 parts by weight of calcined kaolin, 12 to 17 parts by weight of calcium sulfoaluminate (CSA), 6.5 to 8.0 parts by weight of glauberite, and 0.05 to 2.0 parts by weight of fluosilicate salt (K_2SiF_6).
