Premixed recycled aggregate pervious concrete and preparation method thereof
The invention provides premixed recycled aggregate pervious concrete and a preparation method thereof, and relates to the technical field of concrete processing. Comprising the following components in percentage by weight: 50-70% of recycled aggregate; cement: 300 to 400 kg/m < 3 >; the water is determined according to a water-binder ratio, and the water-binder ratio is 0.45-0.55; additives: a water reducing agent, an anti-freezing agent and an anti-cracking agent, wherein the total amount does not exceed 5% of the amount of the cement; the mineral admixture comprises slag powder and fly ash, and the total amount of the mineral admixture does not exceed 30% of the use amount of the cement; the recycled aggregate is used for replacing part of natural aggregate, the material cost is reduced, by optimizing the mixing proportion and the preparation method, the strength, durability and water permeability of the concrete are improved, consumption of natural resources is reduced, environmental pollution is reduced, the mixing proportion and the preparation method are optimized, and the cost is reduced. The working performance of the concrete is improved, the construction difficulty is reduced, and the concrete has remarkable advantages in the aspects of cost, performance, environmental protection property and construction efficiency.
本发明提供一种预拌再生骨料透水混凝土及其制备方法，涉及混凝土加工技术领域。包括以下组分按重量比：再生骨料：50％至70％；水泥：300至400kg/m3；水：根据水胶比确定，水胶比为0.45至0.55；外加剂：减水剂、防冻剂、防裂剂，总量不超过水泥用量的5％；矿物掺合料：矿渣粉、粉煤灰，总量不超过水泥用量的30％；颜料：高性能颜料，用于改善颜色一致性本发明中，使用再生骨料替代部分天然骨料，降低材料成本，通过优化配合比和制备方法，提高混凝土的强度、耐久性和透水性能，减少对天然资源的消耗，降低环境污染，优化配合比和制备方法，提高混凝土的工作性能，降低施工难度，本发明在成本、性能、环保性和施工效率方面均具有显著优势。
