    • PURPOSE: A carbon dioxide reduction type high-flowable ultra-low heat concrete composition is provided to lower emission rate of carbon dioxide during production process and enhance intensity, fluidity, and low exothermicity. CONSTITUTION: A carbon dioxide reduction type high-flowable ultra-low heat concrete composition comprises 400-520kg/m of binder, 130-150kg/m of water, 850-940 kg/m of fine aggregate, 800-900kg/m of coarse aggregate, and 4-10kg/m of superplasticizer. The binder comprises 50-83 parts by weight of ground granulated blast-furnace slag, 5-38 parts by weight of fly ash, and 10-25 parts by weight of alkali activator, and 1-5 parts by weight of sulfate powder. The binder is premixed in a container fixed type high speed mixer with 2,000-2,200rpm for 120-150 seconds. A fine aggregate percentage(S/a) is 25-40% and a replacement rate(W/B) is 48.6-54%. 0.8-2 parts by weight of the high ranged water reducing admixture is mixed based on 100.0 parts by weight of the binder.
    • 目的:提供二氧化碳还原型高流动超低热混凝土组合物,以降低生产过程中二氧化碳的排放速率,增强强度,流动性和低放热性。 构成:二氧化碳还原型高流动超低热混凝土组合物包括粘合剂400-520kg / m 3,水分130-150kg / m,细骨料850-940kg / m,粗骨料800-900kg / m 2 骨料和4-10kg / m的超增塑剂。 粘合剂包含50-83重量份磨碎的高炉渣,5-38重量份粉煤灰和10-25重量份碱活化剂和1-5重量份硫酸盐粉末。 粘合剂在2000-2200rpm的容器固定式高速混合机中预混合120-150秒。 细总比例(S / a)为25-40%,置换率(W / B)为48.6-54%。 基于100.0重量份的粘合剂将0.8-2重量份的高范围减水混合物混合。
