Polyethylene glycol modified geopolymer concrete and preparation method thereof
The invention is applicable to the technical field of geopolymer concrete, and provides polyethylene glycol modified geopolymer concrete, which is prepared from the following raw materials in parts by weight: 30 to 70 parts of slag, 30 to 70 parts of fly ash, 25 to 35 parts of water, 1.8 to 3.4 parts of sodium hydroxide, 20 to 35 parts of water glass and 0.2 to 1 part of polyethylene glycol. The invention also provides a preparation method of the geopolymer concrete modified by polyethylene glycol. According to the present invention, the geopolymer concrete is prepared by doping a large amount of fly ash, such that the resource utilization of the industrial waste can be achieved, the cement consumption can be saved, the influence on the natural resource can be reduced, the production cost can be reduced, the sustainable development requirement can be met, and the fracture property of the geopolymer concrete can be improved by doping the proper amount of polyethylene glycol; the compression resistance and the tensile strength are remarkably improved, the number and the length of cracks are remarkably reduced, the production cost of the preparation method is low, and the production process is simple.
本发明适用于地聚物混凝土技术领域，提供了一种采用聚乙二醇改性的地聚物混凝土，包括以下重量份的原料：矿渣30‑70份、粉煤灰30‑70份、水25‑35份、氢氧化钠1.8‑3.4份、水玻璃20‑35份和聚乙二醇0.2‑1份。本发明还提供了一种采用聚乙二醇改性的地聚物混凝土的制备方法。本发明掺入大量粉煤灰制备地聚物混凝土，可实现工业废弃物的资源化利用，还可以节省水泥用量，减少对自然资源所产生的影响，降低生产成本，符合可持续发展的要求，并掺入适量的聚乙二醇，可以改善地聚物混凝土的断裂性能，使其具有较高韧性，显著提高其抗压和抗拉强度，使裂缝的数量和长度显著减少，制备方法生产成本低，生产过程简单。
