Geopolymer-based foam concrete for roads and preparation method of geopolymer-based foam concrete
The invention discloses geopolymer-based foam concrete for roads and a preparation method of the geopolymer-based foam concrete, the concrete comprises the following components in parts by weight: 100 parts of a gelling raw material, 5-10 parts of an alkali activator, 50-60 parts of water, 0.2-0.4 part of a foaming agent and 0.02-0.05 part of a foam stabilizer, the gelling raw material comprises cement and a silicon-aluminum raw material, and the mass ratio of the cement to the silicon-aluminum raw material is 3: 1-1: 1. The advantages of the geopolymer and the foam concrete are combined, and by optimizing the formula, the concrete is light in weight, heat-resistant, good in stability, good in fluidity and high in compressive strength which is far greater than standard strength (0.6 MPa), and is particularly suitable for road paving. The preparation method is simple, the construction time is short, materials are simple and easy to obtain, solid waste can be utilized, resources are saved, and the cost is reduced.
本发明公开了一种道路用地聚合物基泡沫混凝土及其制备方法，所述混凝土包括以下重量份的组份：胶凝原料100份，碱激发剂5～10份，水50～60份，发泡剂0.2～0.4份，稳泡剂0.02～0.05份，所述胶凝原料包括水泥和硅铝质原料，水泥与硅铝质原料的质量比为3:1～1:1。本发明结合了地聚合物与泡沫混凝土的优势，通过优化配方，使该混凝土质轻、耐热、稳定性好、流动度好，抗压强度高，远大于规范强度(0.6MPa)，特别适用于道路铺设用。所述制备方法简单，施工时间短，材料简单易得，能够固废利用，既节约资源又降低成本。
