Multi-grading composite mineral admixture with core-shell structure and preparation process of multi-grading composite mineral admixture
The invention relates to a multi-grading core-shell structure composite mineral admixture and a preparation process thereof. The raw materials comprise an activating agent and a mineral admixture in a mass ratio of 1: 15000-1: 5000, the mineral admixture is prepared from the following components in parts by mass: 300 to 500 parts of a high-iron admixture, 500 to 700 parts of an aluminum-rich admixture and 500 to 1000 parts of a high-calcium admixture; the activating agent comprises the following components in parts by mass: 20-50 parts of a functional complexing agent and 10-70 parts of a nano nucleating agent. The mixed composite admixture has a core-shell structure, the dissolution of iron and aluminum ions is excellent, the effective utilization rate of the admixture in a cement system is improved, and when the mixing amount is 30%, the performance of the admixture is close to or even exceeds the performance of PI52.5 cement.
本发明涉及一种多级配核壳结构复合矿物掺合料及其制备工艺，原料包括质量比为1:15000～1:5000的活化剂与矿物掺合料；按质量份数计，所述矿物掺合料包括300～500份的高铁掺合料、500～700份的富铝掺合料和500～1000份的高钙掺合料；按质量份数计，所述活化剂包括20～50份的功能络合剂和10～70份的纳米成核剂。本发明混合后的复合掺合料均具有核壳结构，铁铝离子溶出优异，提高其在水泥体系中的有效利用率，在掺量30％时，接近甚至超过PⅠ52.5水泥性能。
