Environment-friendly concrete and preparation method thereof
The invention discloses environment-friendly concrete, which is prepared from the following raw materials in parts by weight: 26 to 27 parts of cement, 38 to 41 parts of river sand, 8 to 8.5 parts of regenerated PET (Polyethylene Terephthalate) powder, 4.5 to 5 parts of fly ash, 2.7 to 3.25 parts of maleic anhydride grafted polyethylene wax, 1.45 to 1.8 parts of phosphorus-containing organic matters, 1.8 to 1.9 parts of thickening agents and 12 to 14 parts of water. In addition, the invention also discloses a preparation method of the environment-friendly concrete, and the preparation method comprises the following steps: mixing the cement, the river sand, the regenerated PET powder, the fly ash and the water to prepare a mixture A; mixing the maleic anhydride grafted polyethylene wax with a phosphorus-containing organic matter to prepare a mixture B; and adding the mixture B and the thickening agent into the mixture A, and uniformly stirring to obtain the environment-friendly concrete. The concrete prepared by the invention is relatively good in workability, relatively high in compressive strength and relatively good in anti-freezing performance.
本申请公开了一种环保型混凝土，按重量份数计，其原料组成包括：水泥26～27份，河砂38～41份，再生PET粉末8～8.5份，粉煤灰4.5～5份，马来酸酐接枝聚乙烯蜡2.7～3.25份，含磷有机物1.45～1.8，增稠剂1.8～1.9份，水12～14份。此外，本申请还公开了一种环保型混凝土的制备方法，包括如下步骤：将所述水泥、所述河砂、所述再生PET粉末、所述粉煤灰和所述水混合，制得混合物A；将所述马来酸酐接枝聚乙烯蜡和含磷有机物混合，制得混合物B；将所述混合物B和所述增稠剂加入所述混合物A中，搅拌均匀，制得所述环保型混凝土。本申请所制得的混凝土和易性能较佳、抗压强度较高、防冻性能较好。
