Steam-curing-free concrete prefabricated part as well as preparation method and application thereof
The invention provides a steam-curing-free concrete prefabricated part and a preparation method and application thereof, and belongs to the technical field of building materials, and the steam-curing-free concrete prefabricated part is prepared from the following raw materials in parts by mass: 40-60 parts of steel fiber mixed filaments, 550-650 parts of cement, 250-300 parts of mineral powder, 100-150 parts of silica fume, 1000-1200 parts of aggregate, 20-30 parts of an additive and 150-170 parts of water. The mineral powder, silica fume and other solid waste materials are used, solid waste resource utilization is achieved, good environmental benefits are achieved, and the national solid waste resource development strategy is met; by replacing quartz sand with the machine-made sand, the cost of the ultra-high-performance concrete small prefabricated part is effectively reduced, high-added-value utilization of the machine-made sand in high-performance concrete is achieved, exploitation of natural sand is reduced, and the method has a positive effect on ecological balance protection.
本发明提供了一种免蒸养混凝土预制构件及其制备方法和应用，属于建筑材料技术领域，由包含下列质量份数的原料制备得到：钢纤维混丝40～60份、水泥550～650份、矿粉250～300份、硅灰100～150份、骨料1000～1200份、外加剂20～30份、水150～170份。本发明使用矿粉、硅灰等固废材料，实现了固体废弃物资源化利用，具有良好的环境效益，符合国家固废资源发展战略；利用机制砂替代石英砂，有效的降低超高性能混凝土小型预制构件的成本，既实现了机制砂在高性能混凝土中的高附加值的利用，又降低了天然砂的开采，对于保护生态平衡具有积极的作用。
