Zeolite powder-based high-activity admixture and preparation method thereof
The invention discloses a zeolite powder-based high-activity admixture and a preparation method thereof, the zeolite powder, silicon powder, a clinker and a DEIPA-TEA grinding aid reinforcing agent are used as raw materials, and the zeolite powder-based high-activity admixture is prepared by a mixed grinding process according to a certain proportion. According to the method, aiming at the problem of insufficient early activity of zeolite powder, the zeolite powder is activated and excited by using the DEIPA-TEA grinding aid reinforcing agent, so that the early high-activity admixture taking the zeolite powder as a main material is prepared, and the early activity index of the zeolite powder can be increased by 4-12%, so that the compressive strength of the admixture is enhanced; the high-activity admixture is suitable for high-performance concrete, the utilization rate of the zeolite powder is increased, the cost of the concrete is reduced, and the high-activity admixture is suitable for industrial popularization and application.
本发明公开了一种以沸石粉为主的高活性掺合料及其制备方法，以沸石粉、硅粉、熟料和DEIPA‑TEA助磨增强剂为原料，按一定比例经过混磨工艺配制得到一种以沸石粉为主的高活性掺合料。本发明方法针对沸石粉早期活性不足的问题，利用DEIPA‑TEA助磨增强剂活化激发沸石粉，制得一种以沸石粉为主的早期高活性掺合料，能够使沸石粉早期活性指数提高4%～12%，以增强掺合料的抗压强度；本发明的高活性掺合料适用于高性能混凝土，提高沸石粉利用率，降低混凝土成本，适宜工业推广和应用。
