High-performance environment-friendly concrete and preparation method thereof
The invention discloses high-performance environment-friendly concrete and a preparation method thereof. The method is characterized by comprising the following steps: (1) crushing, grinding and screening the construction waste to obtain coarse aggregate and fine aggregate; (2) mixing cement, pyrolytic carbon, foam glass, a mineral admixture, reinforced fibers, cellulose, a binder, a water reducing agent and water, and uniformly stirring to prepare a mixture; (3) adding the coarse aggregate and the fine aggregate into the mixture obtained in the step (2), and uniformly stirring to obtain slurry; and (4) pouring and molding the slurry obtained in the step (3) to obtain the high-performance environment-friendly concrete. According to the invention, resource utilization of the construction waste is realized, and the prepared high-performance environment-friendly concrete has relatively good compressive strength, frost resistance, thermal insulation and crack resistance, and is low in cement consumption, low in production cost, green and environment-friendly.
本发明公开了一种高性能环保混凝土及其制备方法。其特征如下：(1)将建筑垃圾进行破碎、研磨和分筛，获得粗骨料和细骨料；(2)将水泥、热解炭、泡沫玻璃、矿物掺和料、增强纤维、纤维素、粘结剂、减水剂和水混合，搅拌均匀，制备成混合物；(3)将粗骨料和细骨料加入步骤2的混合物中，搅拌均匀，得到浆料；(4)将步骤3的浆料浇筑成型得到高性能环保混凝土。该发明实现了对建筑垃圾的资源化利用，制备的高性能环保混凝土具有较好的抗压强度、抗冻性能、保温和抗裂性能，而且水泥用量少，生产成本低、绿色环保。
