Green and environment-friendly concrete and preparation method thereof
The invention relates to the technical field of concrete, and discloses green and environment-friendly concrete and a preparation method thereof. Comprising the following components in parts by weight: 400 to 600 parts of cement, 600 to 800 parts of medium sand, 300 to 500 parts of raw waste slurry, 60 to 90 parts of fly ash, 120 to 150 parts of mineral powder, 500 to 700 parts of water, 10 to 15 parts of a polycarboxylic acid water reducing agent, 1 to 4 parts of a defoaming agent XP-0015, 4 to 6 parts of a silicate cement mucilage preservative BX-001, 3 to 5 parts of a silicate high-alkali waste slurry activation modifier and 2 to 6 parts of modified chitosan adsorption balls. The preparation method comprises the following steps: adding raw waste slurry, a defoaming agent XP-0015, a silicate cement mucilage preservative BX-001, a silicate high-alkali waste slurry activation modifier and modified chitosan adsorption balls into a stirrer according to a ratio, and stirring for 3-5 hours to obtain pretreated raw waste slurry; the cement, the medium sand, the fly ash, the mineral powder, the water, the polycarboxylate superplasticizer and the pretreated raw waste slurry are added into a stirrer according to the proportion to be stirred, and the green and environment-friendly concrete is obtained and has good environment friendliness, workability, crack resistance, cost reduction and synergism.
本发明涉及混凝土技术领域，且公开了一种绿色环保混凝土及其制备方法，包括以下重量组分：400‑600份水泥、600‑800份中砂、300‑500份原生废浆、60‑90份粉煤灰、120‑150份矿粉、500‑700份水、10‑15份聚羧酸减水剂、1‑4份消泡剂XP‑0015、4‑6份硅酸盐水泥胶浆保鲜剂BX‑001、3‑5份硅酸盐高碱废浆活化改性剂、2‑6份改性壳聚糖吸附球；按配比将原生废浆、消泡剂XP‑0015、硅酸盐水泥胶浆保鲜剂BX‑001、硅酸盐高碱废浆活化改性剂、改性壳聚糖吸附球加入到搅拌机中，搅拌3‑5h，得到预处理的原生废浆；按配比将水泥、中砂、粉煤灰、矿粉、水、聚羧酸减水剂、预处理的原生废浆加入到搅拌机中进行搅拌，得到绿色环保混凝土，具有较好的环保性、和易性、抗裂性、降本增效性。
