Low-shrinkage recycled concrete and preparation method thereof
The invention belongs to the technical field of concrete, and particularly discloses low-shrinkage recycled concrete and a preparation method thereof. The low-shrinkage recycled concrete is prepared from the following raw materials in parts by weight: 120 to 180 parts of cement, 60 to 120 parts of construction waste materials, 20 to 35 parts of composite fiber pulp, 30 to 50 parts of fly ash, 30 to 80 parts of fine aggregate, 10 to 15 parts of sepiolite fiber, 1 to 3 parts of polycarboxylic acid water reducing agent and 150 to 200 parts of water, the building waste material is prepared from the following raw materials in parts by weight: 40 to 80 parts of waste building bricks, 15 to 45 parts of gypsum, 10 to 20 parts of waterborne epoxy resin, 6 to 25 parts of carbon fibers, 15 to 30 parts of chitosan microcapsules, 20 to 40 parts of silicon dioxide sol and 100 to 200 parts of water. The low-shrinkage recycled concrete prepared in the invention has good strength, compactness and low shrinkage rate.
本申请属于混凝土技术领域，具体公开了一种低收缩再生混凝土及其制备方法。低收缩再生混凝土，以重量份数计，包括以下原料：120‑180份水泥、60‑120份建筑废弃物料、20‑35份复合纤维浆、30‑50份粉煤灰、30‑80份细骨料、10‑15份海泡石纤维、1‑3份聚羧酸减水剂和150‑200份水；所述建筑废弃物料包括以下重量份的原料：40‑80份废弃建筑砖块、15‑45份石膏、10‑20份水性环氧树脂、6‑25份碳纤维、15‑30份壳聚糖微胶囊、20‑40份二氧化硅溶胶和100‑200份水。本申请中制备的低收缩再生混凝土具有较好的强度、密实性和低收缩率。
