High-strength anti-crack recycled concrete and preparation method thereof
The invention relates to the technical field of concrete, in particular to high-strength anti-crack recycled concrete and a preparation method thereof. The high-strength anti-cracking recycled concrete is prepared from the following components in parts by mass: 470 to 730 parts of modified cement mortar, 450 to 550 parts of coal gangue, 800 to 1000 parts of modified recycled coarse aggregate, 100 to 200 parts of recycled fine aggregate and 80 to 100 parts of water. The modified cement mortar is prepared from the following components in parts by mass: 200 to 300 parts of modified cement, 200 to 300 parts of gravel, 20 to 30 parts of a water reducing agent and 50 to 100 parts of water. The modified recycled coarse aggregate comprises the following components in parts by mass: 700-800 parts of recycled coarse aggregate and 70-140 parts of a modified epoxy resin adhesive. The recycled coarse aggregate is modified, gaps of the recycled coarse aggregate are filled, the compression resistance of the recycled concrete is improved, and the modified rubber is added into the cement, so that the crack resistance of the recycled concrete is improved.
本发明涉及混凝土技术领域，具体为一种高强度抗裂再生混凝土及其制备方法。一种高强度抗裂再生混凝土包括以下质量组分：470～730份改性水泥砂浆、煤矸石450～550份、800～1000份改性再生粗骨料、100～200份再生细骨料、80～100份水。所述改性水泥砂浆包括以下质量组分：200～300份改性水泥、200～300份砂石、20～30份减水剂、50～100份水。所述改性再生粗骨料包括以下质量组分：700～800份再生粗骨料、70～140份改性环氧树脂胶粘剂。本发明对再生粗骨料进行改性，填充了再生粗骨料的缝隙，改善了再生混凝土的抗压性能，在水泥中添加改性橡胶，改善了再生混凝土的抗裂性能。
