CONCRETE COMPOSITION FOR CARBON DIOXIDE REDUCTION, HIGH FLUDITY AND HIGH DURABILITY

摘要

An early strength expression carbon dioxide reduction concrete composition having high fluidity, low heating, and high durability, with respect to 100 parts by weight of blast-furnace slag fine powder, comprises: 10 to 40 parts by weight of fly ash; 10 to 40 parts by weight of Portland cement; 10 to 40 parts by weight of calcium carbonate; 5 to 20 parts by weight of stone powder; 1 to 10 parts by weight of a vitalization agent; and 1 to 3 parts by weight of a high-range water-reducing agent.
