WATER-REDUCING AGENT FOR LOW HEATING HIGH STRENGTH CONCRETE, ALKALI ION ACTIVATION AGENT FOR LOW HEATING HIGH STRENGTH CONCRETE AND LOW HEATING HIGH STRENGTH CONCRETE COMPOSITE CONTAINING THE SAME

摘要

The present invention provides a water-reducing agent for low-heating high-strength concrete formed of 50 to 70 wt% of maintainer and 30 to 50 wt% of water reducer as polycarboxylic acid, an alkali ion activation agent for low-heating high-strength concrete configured by mixing between 30 to 50 wt% of tri-ethanol-amine (TEA) and 50 to 70 wt% of polypenol-amine (PA), and a low-heating high-strength concrete composition configured to contain 450 to 550 kg/m^3 of binding material (B) formed of 45 to 55 wt% of blast furnace slag fine powder, 25 to 35 wt% of ordinary Portland cement, and 15 to 25 wt% of fly ash; 135 to 175 kg/m^3 of water (W); 700 to 770 kg/m^3 of fine aggregate (S); 850 to 940 kg/m^3 of coarse aggregate (G); 4.05 to 8.25 kg/m^3 of the water-reducing agent for low-heating high-strength concrete; and the alkali ion activation agent for low-heating high-strength concrete, in which the water-binding material ratio (W/B) is 27 to 35% and the fine aggregate ratio (S/a) is 42 to 48%, 0.9 to 1.4 parts by weight of the water-reducing agent for low-heating high-strength concrete is mixed with respect to 100 parts by weight of the binding material (B), and 0.1 part by weight of the alkali ion activation agent for low-heating high-strength concrete is mixed with respect to 100 parts by weight of the binding material (B).
