Modified glued concrete and preparation method thereof
The invention discloses modified glued concrete and a preparation method thereof, and belongs to the field of building material preparation, the modified glued concrete comprises a modified powder material, a modified aggregate, a gluing material and water, and the gluing material comprises polymethylhydrosiloxane, calcium stearate, ferrous chloride and a quaternary ammonium salt dispersant according to a mass ratio of (10-12): (2-5): (1-3): (0.1-0.5). Through modification and compounding of the materials, the strength, toughness, impermeability, durability and corrosion resistance of the concrete are remarkably improved, then the usability of the modified glued concrete is improved, meanwhile, the problem of seepage pollution of chloride ions, fluoride ions, sulfate radicals and heavy metal in solid waste is solved, and the service life of the concrete is prolonged. The waterproof structure has good applicability in the fields of waterproofing of various underground garages, waterproofing of underground grain depots, oil prevention of underground oil depots, stable waterproofing of foundation pits, safety waterproofing of tunnels, safety of mountain slope protection and disaster prevention and control.
本发明公开了一种改性胶合混凝土及其制备方法，属于建筑材料制备领域，改性胶合混凝土包括改性粉体材料、改性集物骨料、胶合材料以及水，其中，胶合材料包括质量比为(10～12)：(2～5)：(1～3)：(0.1～0.5)的聚甲基氢硅氧烷、硬脂酸钙、氯化亚铁以及季铵盐分散剂。本申请通过材料的改性及复配，显著增加混凝土的强度、韧性、防渗透性以及耐久耐腐蚀性，进而增加改性胶合混凝土的使用性，同时，解决了固废中氯离子、氟离子、硫酸根、重金属渗出污染的问题，使其在各类地下车库防水、地下粮库防水、地下油库防油、基坑稳定防水、隧道安全防水、山体护坡安全以及灾害防治领域均具有较好的应用性。
