Integrated cementing material for high-performance low-carbon concrete
The invention discloses an integrated cementing material for high-performance low-carbon concrete. The integrated cementing material is prepared by uniformly dry-mixing the following raw materials in parts by weight: 35-40 parts of Portland cement clinker powder; 5 to 6 parts of high-calcium high-iron belite sulphoaluminate cement clinker powder; 5-10 parts of fine limestone powder; 14 to 20 parts of ground fly ash; 10 to 15 parts of superfine slag powder; 10 to 15 parts of steel slag micro powder; and 5-10 parts of coarse limestone powder. The preparation parameters of the high-calcium, high-iron and high-belite sulphoaluminate cement clinker are as follows: the alkalinity coefficient Cm value is 1.60-1.65, the fCaO is 0.5-1.0%, and the fSO3 is 0.5-1.0%; the mineral composition is as follows: 50%-60% of C2S, 20%-25% of C4A3S, 10%-15% of C6AF2 and 5%-10% of C12A7. According to the integrated cementing material disclosed by the invention, the dosage of the cement clinker is as low as 33-38%, and the 28d strength can reach 41.0-42.0 MPa.
本发明公开了一种高性能低碳混凝土用一体化胶凝材料,由如下重量份的原料干混均匀得到:硅酸盐水泥熟料粉35‑40份;高钙高铁贝利特硫铝酸盐水泥熟料粉5‑6份;细石灰石粉5‑10份;磨细粉煤灰14‑20份;矿渣微粉10‑15份;钢渣微粉10‑15份;粗石灰石粉5‑10份。高钙高铁高贝利特硫铝酸盐水泥熟料的配料参数:碱度系数Cm值1.60~1.65,fCaO0.5~1.0%,fSO30.5~1.0%;矿物组成:C2S 50~60%,C4A3S 20~25%,C6AF210‑15%,C12A75‑10%。本发明一体化胶凝材料,水泥熟料用量低至33‑38%,28d强度可达到41.0‑42.0MPa。
