Chloride ion permeation resistant recycled fine aggregate concrete and preparation method thereof
The invention discloses chloride ion permeation resistant recycled fine aggregate concrete and a preparation method thereof, and belongs to the technical field of building materials, the concrete comprises the following raw material components: 1095-1109 parts of natural coarse aggregate, 445-465 parts of waste concrete recycled fine aggregate, 45-65 parts of waste rubber powder, 40-60 parts of waste glass powder, 260-280 parts of cement, 64-78 parts of fly ash, 35-41 parts of silica fume, 90-98 parts of slag powder, and 0.5-1 part of polyvinyl alcohol. The water reducing agent is prepared from the following components in parts by weight: 0.5-1 part of polyvinyl pyrrolidone, 2.38-7.14 parts of carbon nanotubes, 2.38 parts of a water reducing agent and 190 parts of water. According to the invention, by using different particle sizes of different admixtures, good particle gradation is formed, an advantage complementary effect is exerted, a super-composite superimposed effect is generated, the pore structure of the concrete is optimized, the performance of the concrete is further improved, and meanwhile, decoration waste recycled fine aggregate is used for replacing natural sand, so that the problem of resource shortage of the natural sand is relieved.
本发明公开了一种抗氯离子渗透再生细骨料混凝土及其制备方法，属于建筑材料技术领域，所述混凝土原料组分包括，天然粗骨料1095～1109份，废弃混凝土再生细骨料445～465份、废橡胶粉45～65份、废玻璃粉40～60份，水泥260～280份，粉煤灰64～78份，硅灰35～41份，矿渣粉90～98份，聚乙烯醇0.5～1份，聚乙烯基吡咯烷酮0.5～1份，碳纳米管2.38～7.14份，减水剂2.38份，水190份。本发明通过利用不同掺合料的不同粒径，形成良好的颗粒级配，发挥“优势互补效应”，产生超复合叠加效应，优化了混凝土的孔隙结构，进一步提升了混凝土的性能，同时使用装修垃圾再生细骨料取代天然砂，缓解了天然砂资源紧张的问题。
