Low-carbon concrete and cementing material

The invention relates to the field of concrete, in particular to low-carbon concrete and a cementing material. In order to reduce the carbon emission of concrete and solve the technical problem that the mechanical property of the concrete is difficult to guarantee due to the reduction of the cement consumption, the invention provides low-carbon concrete which comprises the following components in parts by weight: 340-410 parts of a cementing material; 700 to 900 parts of fine aggregate; 1070 to 1300 parts of coarse aggregate; 6-10 parts of an additive; the water-binder ratio is 0.40 to 0.60; the cementing material is prepared from 130 to 150 parts of ordinary Portland cement, 150 to 200 parts of first-grade fly ash and 10 to 40 parts of mineral powder. According to the concrete provided by the invention, the consumption of cement and mineral powder is reduced, the strength grade of the concrete is kept at C30-C40, and 74.7-111.3 kg/m < 3 > of CO2 can be reduced. 本发明涉及混凝土领域，特别涉及一种低碳混凝土及胶凝材料。为降低混凝土碳排放量，解决水泥用量减少
