Method for preparing building material for roadbed and pavement from building solid waste based geopolymer
The invention discloses a method for preparing a building material for a roadbed and a pavement by using a building solid waste-based geopolymer, which comprises the following steps: proportioning a building solid waste-based geopolymer cementing material prepared by using building solid waste as a raw material, building waste-based reclaimed sand, aggregate and water, stirring, forming and maintaining to prepare the building material for the roadbed and the pavement. According to the preparation method, barium hydroxide is adopted as a main exciting agent, high-pressure activation is carried out, the dissolution efficiency of active silicon and aluminum in building solid waste is promoted, a compensating agent is added to promote polymerization, and the building solid waste-based geopolymer cementing material of a compact three-dimensional network structure is obtained. The cementing material has the characteristics of early strength, rapid hardening, durability, corrosion resistance and freeze thawing resistance; the building waste-based reclaimed sand prepared by the preparation method is stable in mechanical property, high in toxic metal ion fixing capacity and applicable to building materials for roadbeds and pavements, and the building waste-based reclaimed sand and the building waste-based reclaimed sand are applied to preparation of the building materials for roadbeds and pavements, so that building solid wastes are fully utilized, and the preparation efficiency is improved.
本发明公开了一种建筑固废基地聚物制备路基路面用建筑材料的方法，将以建筑固废为原料制备的建筑固废基地聚物胶凝材料及建筑垃圾基再生砂与骨料、水经过配料、搅拌、成型、养护，制备得到路基路面用建筑材料。本发明通过采用氢氧化钡为主要激发剂并经高压活化，促进建筑固废中活性硅铝的溶出效率，结合加入补偿剂促进聚合，获得质密三维网络结构的建筑固废基地聚物胶凝材料，该胶凝材料具有早强快硬和耐久耐腐蚀及耐冻融特性，且力学性能稳定，固定有毒金属离子能力强，适用于路基路面用建筑材料，同时本发明还获得建筑垃圾基再生砂，并将两者应用与制备路基路面用建筑材料，实现了对建筑固废的充分利用，提高了制备效率。
