Excitant for high-volume slag cement and preparation method thereof
The invention discloses an activator for high-volume slag cement and a preparation method of the activator, and belongs to the technical field of cement admixtures. The activator comprises the following raw materials in parts by weight: 20-50 parts of an early strength component, 2-5 parts of a reinforcing component, 3-8 parts of a grinding aid component, 0.1-0.5 part of a static elimination component, 0.1-1 part of a stable solubilizing component and 30-70 parts of water. After the activator provided by the invention is added, the 45-micron compressive strength is reduced by 3-3.5%, the 3d compressive strength of cement mortar is increased by 4.1-5.4 MPa, the 28d compressive strength is increased by 5.9-8.9 MPa, and the grinding aiding and enhancing effects are obviously superior to those of a commercially available grinding aid.
本发明公开一种大掺量矿渣水泥用激发剂及其制备方法，属于水泥外加剂技术领域。本发明激发剂包括以下重量份的原料：早强组份20‑50份、增强组份2‑5份、助磨组份3‑8份、静电消除组分0.1‑0.5份、稳定增溶组分0.1‑1份、水30‑70份。加入本发明激发剂后，45μm下降3‑3.5％，水泥胶砂3d抗压强度增长4.1‑5.4MPa，28d抗压强度增长5.9‑8.9MPa，助磨、增强效果均明显优于市售助磨剂。
