Fiber reinforced phase change energy storage concrete and preparation method thereof
The invention discloses fiber reinforced phase change energy storage concrete and a preparation method thereof, and the disclosed fiber reinforced phase change energy storage concrete is prepared from the following raw materials: fine sand, cement, fly ash, a water reducing agent, silicon dioxide (SiO2), phase change microcapsules, polyvinyl alcohol fibers (PVA) and water. According to the method, the microstructure of a matrix in the concrete is improved through the methods of removing coarse aggregate, optimizing fine aggregate, adding a nano modifier and the like, the microcosmic interface performance is improved, meanwhile, a high-performance fiber material is introduced to balance the weakening effect of the microcapsules on the mechanical property of the concrete, and the mechanical property of the concrete is improved. The fiber-reinforced phase-change energy-storage concrete with toughening, reinforcing and phase-change temperature control functions is formed by breaking through the bottleneck of an inverted relationship between mechanical and thermal properties of common energy-storage concrete, the safety-energy-saving integrated reinforcement and transformation technology of existing buildings is enriched, the preparation method is simple and convenient, industrial production is easy, and the fiber-reinforced phase-change energy-storage concrete is suitable for industrial production. The method can be effectively applied to safe and energy-saving integrated reinforcement and reconstruction of large old buildings in China.
本发明公开了一种纤维增强型相变储能混凝土及其制备方法，公开的纤维增强型相变储能混凝土，包含以下原材料：细沙、水泥、粉煤灰、减水剂、二氧化硅(SiO2)、相变微胶囊、聚乙烯醇纤维(PVA)和水。本发明通过去除粗骨料、优化细骨料、加入纳米改性剂等方法改善混凝土内部基体微观结构、提升微观界面性能，同时，引入高性能纤维材以平衡微胶囊对混凝土力学性能的削弱效应，突破普通储能混凝土力学‑热工性能之间的“倒置”关系瓶颈，形成兼具增韧补强和相变控温功能的纤维增强型相变储能混凝土，丰富了既有建筑安全‑节能一体化加固改造技术，且制备方法简便，易于工业化生产，可有效应用于我国大体量老旧建筑的安全、节能一体化加固改造。
