Recycled concrete and preparation method thereof
The invention provides recycled concrete and a preparation method thereof. The recycled concrete is prepared from 15 parts of cement, 5-17 parts of desert sand, 10-28 parts of medium sand, 10-30 partsof recycled aggregate, 20-40 parts of stone, 0.05-0.10 part of a water reducing agent and the balance of water. The invention also relates to a preparation method of the recycled concrete. Accordingto the preparation method, the building waste concrete is used as recycled aggregate, desert sand is used for replacing fine aggregate, the mechanical property of the cement concrete is improved, thepurposes of protecting the environment and saving resources are achieved on the premise that the strength of a test piece is exerted, and a wider development prospect is provided for efficient utilization of building material waste in the future.
本发明提供了一种再生混凝土及其制备方法；包括：水泥15份，沙漠砂5‑17份，中砂10‑28份，再生骨料10‑30份，石子20‑40份，减水剂0.05‑0.10份，余量为水。本发明还涉及前述再生混凝土的制备方法。本发明提供一种利用建筑废弃混凝土作再生骨料、以沙漠砂替代细集料，提高水泥混凝土力学性能的制备方法，在保障试件强度发挥的前提下，达到保护环境，节约资源的目的，为以后建筑材料废弃物的高效化利用，提供更加广阔的发展前景。
