Durable recycled aggregate concrete and preparation method thereof
The invention relates to the field of concrete, and particularly discloses durable recycled aggregate concrete and a preparation method thereof. The concrete is prepared from the following raw materials: modified recycled coarse aggregate, modified recycled fine aggregate, recycled micro powder, cement, fly ash, mineral powder, reinforced fibers, a water reducing agent, water and epoxy resin emulsion, wherein both the modified recycled coarse aggregate and the modified recycled fine aggregate are obtained by drying after being soaked in a modification solution for 5-6 hours, and the modification solution is prepared from the following raw materials in parts by weight: 8-10 parts of chitosan, 6-8 parts of acetic acid, 100-120 parts of water, 20-30 parts of nano zirconium oxide, 20-30 parts of nano silicon dioxide and 10-20 parts of bentonite; the recycled aggregate concrete prepared in the invention has the advantages of good crack resistance, good mechanical properties and good durability.
本申请涉及混凝土领域，具体公开了一种耐久性再生骨料混凝土及其制备方法。混凝土包括以下原料：改性再生粗骨料、改性再生细骨料、再生微粉、水泥、粉煤灰、矿粉、增强纤维、减水剂、水和环氧树脂乳液；其中改性再生粗骨料和改性再生细骨料均通过改性液浸泡5‑6h后干燥得到，改性液包括以下重量份的原料制成：8‑10份壳聚糖、6‑8份乙酸、100‑120份水、20‑30份纳米氧化锆、20‑30份纳米二氧化硅和10‑20份膨润土；本申请制备的再生骨料混凝土具有抗裂性能好、力学性能好以及耐久性好的优点。
