High-performance geopolymer concrete and preparation method thereof
The invention relates to high-performance geopolymer concrete and a preparation method thereof. The high-performance geopolymer concrete is prepared from fly ash, superfine slag powder, sodium hydroxide, water glass, a water reducing agent, fine aggregate, coarse aggregate, steel fibers and polypropylene fibers. The preparation method comprises the following steps: adding and mixing the componentsof formulation according to a reasonable sequence, adding the polypropylene fibers twice in the mixing process and laying the steel fibers in a layered manner in the concrete pouring process. The high-performance geopolymer concrete has remarkable effects of improving the brittleness of geopolymer concrete, improving the ductility of the geopolymer concrete, saving the fiber consumption and the like.
本发明涉及一种高性能地聚物混凝土及其制备方法。所公开的高性能地聚物混凝土由粉煤灰、矿渣微粉、氢氧化钠、水玻璃、减水剂、细骨料、粗骨料、钢纤维和聚丙烯纤维制备而成。所公开的制备方法是将配方量的各组分按照合理顺序加入拌和，其中聚丙烯纤维是在拌和过程中分两次加入，钢纤维是在混凝土浇筑过程分层铺设。本发明对改善地聚物混凝土的脆性、提升其延性，同时节约纤维用量等有显著作用。
