The invention relates to the field of concrete, and particularly discloses environment-friendly concrete and a preparation method thereof. The environment-friendly concrete is prepared from the following raw materials in parts by weight: 380 to 420 parts of cement, 900 to 1100 parts of hydrophobic modified recycled coarse aggregate, 180 to 220 parts of recycled micro powder, 10 to 50 parts of water reducing agent, 80 to 100 parts of fly ash, 700 to 800 parts of fine aggregate and 100 to 300 parts of water, wherein the hydrophobic modified recycled coarse aggregate is modified by rolling grinding; the preparation method comprises the following steps: fully oscillating and mixing the hydrophobic recycled coarse aggregate and the recycled micro powder, adding the cement, the water reducing agent, the fly ash and the fine aggregate, mixing, uniformly stirring, adding the water, and continuously stirring for 1-2 hours. The environment-friendly concrete has the advantage of improving the strength of the recycled coarse aggregate concrete.
本申请涉及混凝土领域，具体公开了一种环保混凝土及其制备方法。一种环保混凝土包括按重量份计的如下原料：380‑420份水泥、900‑1100份疏水改性再生粗骨料、180‑220份再生微粉、10‑50份减水剂、80‑100份粉煤灰、700‑800份细骨料和100‑300份水，其中疏水改性再生粗骨料通过滚动研磨改性；其制备方法为：先将疏水再生粗骨料与再生微粉充分震荡混合，再加入水泥、减水剂、粉煤灰和细骨料混合后搅拌均匀，加入水继续搅拌1‑2h。本申请的一种环保混凝土具有提高再生粗骨料混凝土的强度的优点。
