Low heating high strength concrete composite

摘要

The present invention relates to a water reducing agent for low-heat type high-strength concrete consisting of 50 to 70 wt% of a retention system and 30 to 50 wt% of a water reducing system as a polycarboxylic acid system, 30 to 50 wt% of TEA (Tri-Ethanol- And 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, which are composed of 50 to 70 wt% of PA (Polyphenol-Amine) 450 to 550 kg / m 3 of the binder (B) Water (W) 135-175 kg / m3; Fine aggregate (S) 700 to 770 kg / m3; Coarse aggregate (G) 850 to 940 kg / m3; Water reducing agent for low-heat type high-strength concrete, 4.05 to 8.25 kg / m3; (W / B) of 27 to 35% and a fine aggregate ratio (S / a) of 42 to 48%, and the low heat generation type high strength concrete The water reducing agent for high strength concrete is mixed with 0.9 to 1.4 parts by weight with respect to 100 parts by weight of the binder (B), and the alkali ion activator for the low heat generating type high strength concrete is mixed with 0.1 part by weight with respect to 100 parts by weight of the binder (B) / RTI
