Superfine powder for concrete and preparation method thereof
The invention relates to the technical field of building materials, and particularly provides superfine powder for concrete and a preparation method of the superfine powder. The superfine powder comprises the following components in parts by weight: 10-50 parts of mineral powder, 5-40 parts of fly ash, 2-35 parts of silica fume, 1-20 parts of stone powder, 5-40 parts of gypsum, 3-25 parts of microbeads, 1-15 parts of a functional additive, 1-12 parts of organic amine, 0.5-8 parts of an exciting agent and 0.1-10 parts of a water reducing agent. The functional additive is a zinc complex containing a siloxane structure. The particle sizes of the components are optimized, a zinc complex containing a siloxane structure is used as a functional additive and the like, the mechanical enhancement and corrosion resistance of the superfine powder on the concrete are improved by utilizing a size effect and an intermolecular interaction, and the resource utilization degree of wastes is also improved.
本申请涉及建筑材料技术领域，具体提供了一种混凝土用超微粉及其制备方法。按照重量份计，所述超微粉的组分包括10‑50份矿粉、5‑40份粉煤灰、2‑35份硅灰、1‑20份石粉、5‑40份石膏、3‑25份微珠、1‑15份功能助剂、1‑12份有机胺、0.5‑8份激发剂、0.1‑10份减水剂；所述功能助剂为含硅氧烷结构的锌络合物。本申请通过优化组分的粒径，使用含硅氧烷结构的锌络合物作为功能助剂等，利用尺寸效应和分子间作用提高超微粉对混凝土的力学增强和耐腐蚀性能的提升，还提高了废弃物的资源化利用程度。
