Residue soil type construction waste regenerated pervious concrete and preparation method thereof
The invention relates to the technical field of concrete, and discloses residue soil type construction waste regenerated pervious concrete and a preparation method thereof.The residue soil type construction waste regenerated pervious concrete is prepared from 850-1250 parts of regenerated residue soil aggregate, 220-380 parts of cement, 60-110 parts of fly ash, 25-55 parts of silica fume, 4-9 parts of a water reducing agent, 6-18 parts of reinforced fibers, 3-7 parts of a pervious additive and 4-9 parts of nano titanium dioxide; the self-repairing coating is prepared from, by weight, 12-35 parts of zeolite powder, 35-65 parts of superfine slag powder, 5-10 parts of magnetic adsorption particles and 3-8 parts of self-repairing microcapsules. By adding the reinforced fibers, the compressive strength is improved, the crack risk is reduced, the permeation coefficient is improved by adding the permeation accelerant, the drainage pressure is relieved, the self-repairing efficiency is improved by utilizing the self-repairing microcapsules, the magnetic adsorption particles are added, the water environment is improved, the composite water reducing agent is adopted, the cost is reduced, and the durability is enhanced.
本发明涉及混凝土技术领域，且公开了一种渣土类建筑垃圾再生透水混凝土及其制备方法，包括再生渣土骨料850份至1250份，水泥220份至380份，粉煤灰60份至110份，硅灰25份至55份，减水剂4份至9份，增强纤维6份至18份，透水助剂3份至7份，纳米二氧化钛4份至9份，沸石粉12份至35份，矿渣微粉35份至65份，磁性吸附颗粒5份至10份，自修复微胶囊3份至8份。本发明通过添加增强纤维，使抗压强度提升，减少裂缝风险，添加透水促进剂使透水系数提高，缓解排水压力，利用自修复微胶囊，自修复效率提升，添加磁性吸附颗粒，改善水环境，采用复合型减水剂，降低成本并增强耐久性。
