Recycled concrete beneficial to improvement of impermeability and preparation method thereof
The invention discloses recycled concrete beneficial to improvement of impermeability and a preparation method of the recycled concrete. The recycled concrete is prepared from 50-90 parts of fly ash, 160-240 parts of cement, 25-45 parts of slag powder, 750-1100 parts of modified recycled coarse aggregate, 300-550 parts of natural fine aggregate, 90-120 parts of modified recycled PET (Polyethylene Terephthalate) plastic particles, 5-8 parts of an additive and water, the additive comprises a water reducing agent, an air entraining agent, an early strength agent and a waterproof agent, and the recycled concrete comprises the following components in parts by weight: 75 parts of fly ash, 210 parts of cement, 30 parts of slag powder, 960 parts of modified recycled coarse aggregate, 320 parts of natural fine aggregate, 95 parts of modified recycled PET plastic particles, 0.5 part of the water reducing agent, 1.6 parts of the air entraining agent, 7.5 parts of the early strength agent, 2.3 parts of the waterproof agent and water. According to the recycled concrete beneficial to improvement of impermeability and the preparation method thereof, batch and rapid preparation of the recycled concrete is facilitated, the quality of the recycled concrete is ensured, improvement of the impermeability of the recycled concrete is facilitated, and reutilization of the recycled concrete is ensured.
本发明公开了一种有利于改善抗渗性的再生混凝土及其制备方法，所述再生混凝土包括粉煤灰50份‑90份、水泥160份‑240份、矿渣粉25份‑45份、改性再生粗骨料750份‑1100份、天然细骨料300份‑550份、改性再生PET塑料颗粒90份‑120份、添加剂5份‑8份和水；添加剂由减水剂、引气剂、早强剂和防水剂组成，再生混凝土按重量份包括粉煤灰75份、水泥210份、矿渣粉30份、改性再生粗骨料960份、天然细骨料320份、改性再生PET塑料颗粒95份、减水剂0.5份、引气剂1.6份、早强剂7.5份、防水剂2.3份和水。该有利于改善抗渗性的再生混凝土及其制备方法，便于批量快速进行再生混凝土制备，保证再生混凝土的质量，有利于改善再生混凝土的抗渗性能，保证再生混凝土的再利用。
