Phase-change energy-storage geopolymer concrete as well as preparation method and application thereof
The invention relates to the technical field of concrete preparation, in particular to phase change energy storage geopolymer concrete as well as a preparation method and application thereof. The concrete comprises 32-50 parts of fly ash, 28-40 parts of red mud, 20-34 parts of water glass, 10-38 parts of alkali metal hydroxide, 20-35 parts of steel slag powder, 43-52 parts of steel slag aggregateand 22-35 parts of phase change spherical particles, the phase change spherical particles comprise geopolymers and phase change materials, and the geopolymers comprise the following components in parts by weight: 20-30 parts of fly ash, 20-30 parts of water glass, 5-20 parts of potassium hydroxide, 12-25 parts of steel slag powder, 1-5 parts of barium chloride, 12-20 parts of graphite powder, 2-10parts of boric acid and 10-18 parts of water. According to the phase-change energy-storage geopolymer concrete, the phase-change spherical particle surface layer can be effectively combined with theconcrete and is not prone to cracking, and the problem that the compatibility of a phase-change material and a concrete matrix is poor is solved.
本发明涉及混凝土制备技术领域，具体涉及一种相变储能地聚合物混凝土及其制备方法及其应用。所述混凝土包括：粉煤灰32‑50份、赤泥28‑40份、水玻璃20‑34份、碱金属氢氧化物10‑38份、钢渣粉20‑35份、钢渣骨料43‑52份、相变球粒22‑35份，且该相变球粒包括地聚合物和相变材料，该地聚合物包括：粉煤灰20‑30份、水玻璃20‑30份、氢氧化钾5‑20份、钢渣粉12‑25份、氯化钡1‑5份、石墨粉12‑20份、硼酸2‑10份、水10‑18份。本发明相变储能地聚合物混凝土中相变球粒表层与混凝土可有效结合，不易开裂，解决了相变材料与混凝土基体兼容性较差的问题。
