摘　　要：以较低水泥用量180kg/m3,大掺量矿渣粉、粉煤灰研制出C50高强高性能自密实混凝土,混凝土排碳量仅为88.136kg/m3,是普通自密实混凝土的49.52%。试验表明该混凝土和易性好、流动性保持性好,性能与采用高水泥用量配制出的自密实混凝土相当。该文研究的自密实混凝土大大降低了水泥用量,降低混凝土的排碳量,同时大大降低混凝土成本。This paper developed the C50 high-strength high-performance self-compacting concrete by low amount of cement with 180 kg/m3, large amount of slag powder and fly ash. Its carbon emissions is 88. 136 kg/m3, the 49. 52 percent of common self-compacting concrete. The tests show that this concrete has good workability, and its liquidity loss is smaller. Its performance is the same as the self-compacting concrete with high content of cementitious material. The self-compacting concrete developed by this paper reduces the amount of cement greatly, the carbon emissions, and costs of concrete significantly.
