Low-heat slag cement
The invention belongs to the technical field of slag cement, and particularly relates to low-heat slag cement. The invention relates to low-heat slag cement, which is prepared from the following components in percentage by mass: 30.5 to 47.5 percent of clinker, 3.3 to 5.5 percent of limestone, 1.2 to 2.0 percent of gypsum and the balance of superfine mineral powder, totaling 100 percent. According to the present invention, the formula with the excellent quality index is obtained through the screening of the low-heat slag cement formula, the 7d compressive strength is not less than 19.0 MPa and the 28d compressive strength is not less than 40.0 MPa under the condition of meeting the GB/T 42531-2023 standard requirement, and the low hydration heat value is provided, such that the important significance is provided for the development of the low-heat slag cement.
本发明属于矿渣水泥技术领域，具体涉及一种低热矿渣水泥。一种低热矿渣水泥，以质量百分比计，所述低热矿渣水泥由以下成分制备而成：熟料30.5‑47.5%、石灰石3.3‑5.5%、石膏1.2‑2.0%，超细矿粉补充至100%。本发明通过低热矿渣水泥配方的筛选，得到质量指标较优的配方，在满足GB/T 42531‑2023标准要求的情况下，实现7d抗压强度不低于19.0MPa，28d抗压强度不低于40.0MPa，且具有较低的水化热值，这对开发低热矿渣水泥具有重要意义。
