Building solid waste concrete and preparation method thereof
The invention provides building solid waste concrete, which belongs to the technical field of building waste reutilization, and comprises the following components in parts by weight: 77 to 90 parts of building solid waste aggregate, 5 to 15 parts of cement, 0.5 to 1.5 parts of quick lime, 0.5 to 1.5 parts of auxiliary agent, and 8 to 12 parts of water, wherein the building solid waste aggregate comprises building solid waste coarse aggregate and building solid waste fine aggregate; the particle size of the building solid waste coarse aggregate is 8-25mm, and the particle size of the building solid waste fine aggregate is 4.5-8.5 mm; the mass ratio of the building solid waste coarse aggregate to the building solid waste fine aggregate is (20-30): (32-45). The particle sizes of the building solid waste coarse aggregate and the building solid waste fine aggregate are higher than those of common aggregate, meanwhile, the high-content fine aggregate is added, the use of low-dosage cement under the overall high aggregate proportion can be met, the building use requirement of concrete is met, the environment-friendly effect is improved, and the production cost is reduced.
本发明提供了一种建筑固废混凝土，属于建筑废弃物再利用技术领域，包括如下重量份数的组分：建筑固废骨料77～90份、水泥5～15份、生石灰0.5～1.5份、助剂0.5～1.5份和水8～12份；所述建筑固废骨料包括建筑固废粗骨料和建筑固废细骨料；所述建筑固废粗骨料的粒径为8～25mm，所述建筑固废细骨料的粒径为4.5～8.5mm；所述建筑固废粗骨料和建筑固废细骨料的质量比为(20～30)：(32～45)。本发明采用的建筑固废粗骨料和建筑固废细骨料的粒径均高于普通骨料，同时添加加较高含量的细骨料可满足整体高骨料占比下低用量水泥的使用，满足了混凝土的建筑使用要求，提升了环保效果，降低了生产成本。
