Recycled concrete and preparation method thereof
The invention discloses recycled concrete which comprises the following components in parts by mass: 40-50 parts of recycled coarse aggregate, 20-30 parts of fine aggregate, 2-4 parts of a water reducing agent, 3-6 parts of talcum powder, 15-20 parts of cement and 8-10 parts of water. According to the recycled concrete, the preparation of the recycled coarse aggregate, the pretreatment of the recycled coarse aggregate and the fine aggregate and other methods are improved so that the strength of the recycled concrete can be improved, and the water absorption rate is reduced.
本发明公开了一种再生混凝土，以质量份数计包括：再生粗骨料40‑50份、细骨料20‑30份、减水剂2‑4份、滑石粉3‑6份、水泥15‑20份、水8‑10份。本发明提供的再生混凝土，通过再生粗骨料的制备，以及再生粗骨料与细骨料的预处理等方法改进，可以提高再生混凝土的强度，同时减小吸水率。
