Reclaimed sand high-performance concrete and preparation method thereof
The invention relates to the field of building materials, and particularly discloses reclaimed sand high-performance concrete and a preparation method thereof. The regenerated sand high-performance concrete is prepared from the following components in parts by weight: 800 to 900 parts of modified regenerated sand, 600 to 650 parts of cement, 400 to 500 parts of modified fly ash, 50 to 80 parts of regenerated fiber, 30 to 40 parts of MgO expanding agent, 20 to 30 parts of water reducing agent and 100 to 200 parts of floating bead, the modified reclaimed sand is prepared by modifying reclaimed sand obtained by treating waste construction waste after demolition of a building; the modified fly ash is prepared by treating and modifying coal-fired waste fly ash. The reclaimed sand high-performance concrete is good in comprehensive performance, has the characteristics of being high in strength, low in water absorption rate and excellent in durability, and can relieve the problem of shortage of natural sand resources; in addition, the preparation method provided by the invention can be used for preparing the reclaimed sand high-performance concrete with good comprehensive performance.
本申请涉及建筑材料领域，具体公开了一种再生砂高性能混凝土及其制备方法。一种再生砂高性能混凝土，以重量份计，包括800‑900份改性再生砂、600‑650份水泥、400‑500份改性粉煤灰、50‑80份再生纤维、30‑40份MgO膨胀剂、20‑30份减水剂和100‑200份漂珠；所述改性再生砂由建筑拆除后的废旧建筑垃圾经处理得到的再生砂改性后制成；所述改性粉煤灰由燃煤废弃物粉煤灰经处理改性后制成。本申请的一种再生砂高性能混凝土综合性能较好，具有强度较高、吸水率较低、耐久性优秀的特点，能够缓解天然砂资源短缺的问题；另外，本申请的制备方法能够制备出综合性能良好的再生砂高性能混凝土。
