The invention relates to the field of geopolymer materials, in particular to a multi-solid-waste-based chlorine-salt-corrosion-resistant geopolymer concrete material and a preparation method thereof. The chlorine salt corrosion resistant geopolymer is composed of solid powder, aggregate and an alkali activator, wherein the solid powder is composed of fly ash and slag, the aggregate is iron tailings and fine sand, and the alkali activator is prepared by mixing solid sodium hydroxide, carbide slag, water glass and water. According to the invention, fly ash, slag, iron tailings and fine sand are used as main raw materials and are mixed with an alkali activator to obtain a novel chlorine salt corrosion resistant concrete material; the invention has the advantages of simple process, no CO2 emission and favorable mechanical properties, can meet the use requirements of common marine concrete buildings, also realizes the resource utilization of fly ash and blast furnace iron smelting slag, can effectively solve the problem of environmental pollution caused by stockpiling of fly ash and slag, and has favorable application prospects.
本发明涉及地聚物材料领域，具体涉及一种多固废基耐氯盐腐蚀地聚物混凝土材料及其制备方法。该耐氯盐腐蚀地聚物由固体粉料、骨料及碱激发剂构成；其中固体粉料是由粉煤灰与炉渣组成，骨料为铁尾矿和细沙，碱激发剂由固体氢氧化钠、电石渣、水玻璃与水混合制成。本发明以粉煤灰、炉渣、铁尾矿和细沙为主要原料，通过与碱激发剂混合，得到一种新型耐氯盐腐蚀混凝土材料；其工艺简单、无CO2排放，具有良好的力学性能，能满足一般海工混凝土建筑使用需求，同时也实现了对粉煤灰和高炉冶铁炉渣的资源化利用，可有效解决粉煤灰与炉渣堆存带来的环境污染问题，具有较好的应用前景。
