Anti-crack environment-friendly concrete and preparation process thereof
The invention discloses anti-crack environment-friendly concrete, which is prepared from the following raw materials in parts by weight: 280 to 320 parts of cement, 142 to 156 parts of water, 550 to 680 parts of sand, 700 to 800 parts of gravel, 30 to 40 parts of fly ash, 6 to 8 parts of additives and 60 to 80 parts of polypropylene anti-crack fibers. Cement, water, sand, sandstone, fly ash and an additive are mixed, then polypropylene anti-crack fibers are added into the mixture, the polypropylene anti-crack anti-seepage short fibers are high-strength bunchy monofilament organic fibers formed by processing fiber-grade polypropylene as a raw material through a special technology, and after the polypropylene anti-crack fibers are combined into concrete, the anti-crack performance of the concrete is improved. The anti-cracking performance of the concrete can be improved.
本发明公开了一种抗裂环保混凝土，包括以下重量份原料：水泥280‑320份、水142‑156份、砂550‑680份、碎石700‑800份、粉煤灰30‑40份、外加剂6‑8份，还包括聚丙烯抗裂纤维60‑80份。在水泥、水、砂、砂石、粉煤灰、外加剂混合后，再在其中加入聚丙烯抗裂纤维，由于聚丙烯抗裂防渗短纤维是采用纤维级聚丙烯为原料，经特殊工艺加工处理而形成的高强度束状单丝有机纤维，在将聚丙烯抗裂纤维结合入混凝土中后，即可提升混凝土的抗裂性能。
