High-strength baking-free brick prepared from construction waste and preparation method of high-strength baking-free brick
The invention relates to the field of construction waste resource utilization, and discloses a high-strength baking-free brick prepared from construction waste and a preparation method thereof.The high-strength baking-free brick is prepared from, by weight, 60-70 parts of construction waste aggregate, 20-30 parts of cement, 6-10 parts of polyurea resin, 1-5 parts of water reducing agent and 5-10 parts of water; the polyurea resin comprises a component A and a component B in a mass ratio of (1-3): 1, the component A is a secondary amine component, and the component B is an isocyanate curing agent. The building waste is used as the aggregate, the cement is used as the cementing material, and the polyurea resin is added as the reinforcing agent, so that the prepared baking-free brick has excellent mechanical properties, water resistance and the like, and the reduction and resource utilization of the building waste can be realized.
本发明涉及建筑垃圾资源化利用领域，公开了一种利用建筑垃圾制备的高强免烧砖及其制备方法，以重量份计，原料包括：建筑垃圾骨料60～70份，水泥20～30份，聚脲树脂6～10份，减水剂1～5份，水5～10份；所述的聚脲树脂包括质量比为1～3:1的A组分和B组分，A组分为仲胺组分，B组分为异氰酸酯固化剂。本发明以建筑垃圾作为骨料，水泥作为胶凝材料，并添加聚脲树脂作为增强剂，制得的免烧砖具有优异的力学性能和抗水性等性能，可以实现建筑垃圾的减量化、资源化利用。
