Geopolymer mortar reinforcing material as well as preparation method and application thereof
The geopolymer mortar reinforcing material comprises the following raw materials: fly ash, slag, fine aggregate, water, water glass, sodium hydroxide, polyvinyl alcohol fiber and a water reducing agent, the concrete is prepared from the following raw materials in parts by weight: 420 to 560 parts of fly ash, 140 to 280 parts of slag, 210 to 420 parts of fine aggregate, 140 to 161 parts of water, 150 to 200 parts of water glass, 60 to 80 parts of sodium hydroxide, 15 to 30 parts of polyvinyl alcohol fiber and 7 to 10.5 parts of water reducing agent. According to the geopolymer mortar material disclosed by the invention, the cracking characteristic of a concrete member is improved through the proportion design of the matrix, and the polyvinyl alcohol fiber with a proper proportion is matched, so that the high matching of the matrix, the fiber and an interface and the optimization of the fiber toughening efficiency are realized, and the geopolymer mortar material disclosed by the invention has high ductility.
本发明公开了一种地聚物砂浆加固材料，原料包括：粉煤灰、矿渣、细骨料、水、水玻璃、氢氧化钠、聚乙烯醇纤维和减水剂；各原料的组分重量份数为：粉煤灰420‑560份，矿渣140‑280份，细骨料210‑420份，水140‑161份，水玻璃150‑200份，氢氧化钠60‑80份，聚乙烯醇纤维15‑30份，减水剂7‑10.5份。本发明通过基体的配比设计改善混凝土构件的开裂特性，搭配合适配比的聚乙烯醇纤维，实现了基体、纤维、界面的高度匹配和纤维增韧效率的优化，使得本发明的地聚物砂浆材料具有高延性。
