Inorganic recycled concrete aggregate
The invention relates to the field of concrete, and particularly discloses an inorganic recycled concrete aggregate. The concrete is prepared from the following raw materials in parts by weight: 200-280 parts of cement, 100-150 parts of fly ash, 20-60 parts of mineral powder, 950-1500 parts of recycled coarse aggregate, 5-8.4 parts of an additive and 110-145 parts of water; the recycled coarse aggregate is prepared by the following method: I, crushing, cleaning, grading and drying waste concrete blocks to obtain recycled aggregate; II, pretreating the regenerated aggregate with a gelatin solution, and then drying to obtain pretreated regenerated aggregate; and III, retreating the pretreated recycled aggregate with hydrophobic modified silica sol to obtain recycled coarse aggregate. The prepared recycled concrete has the advantage of good mechanical strength.
本申请涉及混凝土领域，具体公开了一种无机再生混凝土集料；由包含以下重量份的原料制成：水泥200‑280份、粉煤灰100‑150份、矿粉20‑60份、再生粗骨料950‑1500份、外加剂5‑8.4份、水110‑145份；再生粗骨料采用如下方法制备而成：Ⅰ废旧混凝土块经破碎、清洗、分级、烘干后制得再生集料；Ⅱ再生集料经明胶溶液预处理，然后经干燥，制得预处理再生集料；Ⅲ预处理再生集料经疏水改性硅溶胶再处理，制得再生粗骨料；使制得的再生混凝土具有机械强度好的优点。
