Environment-friendly anti-crack concrete and preparation method thereof
The invention relates to the field of environment-friendly concrete, and particularly discloses environment-friendly anti-crack concrete and a preparation method thereof. The environment-friendly anti-crack concrete is prepared from the following components in parts by weight: 280 to 300 parts of cement, 100 to 120 parts of fly ash, 500 to 550 parts of sand, 600 to 700 parts of fine stone, 100 to 150 parts of water, 2-5 parts of a water reducing agent, 2-5 parts of a reinforcing agent, and 500 to 600 parts of modified recycled aggregate, wherein the modified recycled aggregate is prepared from waste concrete blocks through crushing, acid pickling, calcination, modification and other processes. According to the environment-friendly anti-crack concrete, the waste concrete is recycled, and a special modification treatment process is matched, so that the environment-friendly anti-crack concrete has the advantages of being environmentally friendly and excellent in anti-crack performance at the same time.
本申请涉及环保型混凝土领域，具体公开了一种环保型抗裂混凝土及其制备方法。一种环保型抗裂混凝土，由以下重量份数的组分组成：水泥280‑300份；粉煤灰100‑120份；砂子500‑550份；细石600‑700份；水100‑150份；减水剂2‑5份；增强剂2‑5份；改性再生骨料500‑600份；所述改性再生骨料由废弃混凝土块经粉碎、酸洗、煅烧、改性等工艺处理制得。本申请的环保型抗裂混凝土通过对废弃混凝土进行回收利用，再配合特殊的改性处理工艺，使其同时具有绿色环保，抗裂性能优异的优点。
