More Information
Summary:The invention discloses low-carbon concrete and a preparation method thereof. The low-carbon concrete is prepared from the following components: 180 to 200 parts of silicate cement, 50 to 80 parts of blast furnace slag powder, 70 to 100 parts of fly ash, 600 to 900 parts of sand, 1000 to 1100 parts of stone, 240 to 380 parts of stone powder, 120 to 200 parts of water, 5 to 20 parts of composite admixture and 5 to 10 parts of polycarboxylate superplasticizer, the composite admixture comprises 5 to 10% of dopamine, 1 to 3% of resorcinol, 1 to 3% of a small molecular alcohol amine compound, 0.5 to 1.5% of amino silicon oil, 0.1 to 0.5% of hexadecyl trimethyl ammonium hydroxide, and the balance of water. The admixture has the effects of reducing glue and water, and meanwhile, the early doping efficiency of the fly ash is improved, and the early strength of the concrete is improved. 本发明公开了一种低碳混凝土及其制备方法，包括以下组分：硅酸水泥180～200份、高炉矿渣粉50～80份、粉煤灰70～100份、砂600～900份、石头1000～1100份、石粉240～380份、水120～200、复合外加剂5～20份、聚羧酸减水剂5～10份；所述复合
