Impermeable concrete prefabricated part and preparation process thereof
The invention relates to the technical field of concrete, and particularly discloses an impermeable concrete prefabricated part and a preparation process thereof. According to the technical key point, the anti-seepage concrete prefabricated part is prepared from the following components in parts by weight: 800 to 1000 parts of sand, 800 to 1000 parts of gravel, 400 to 450 parts of cement, 80 to 120 parts of mineral powder, 100 to 150 parts of fly ash, 10 to 15 parts of hydroxypropyl methyl cellulose, 100 to 150 parts of carbonized rice hull ash and 200 to 250 parts of water. The preparation process comprises the following steps: stirring and mixing the sand, the gravel, the cement, the mineral powder, the fly ash, the hydroxypropyl methyl cellulose, the carbonized rice hull ash and the water to obtain mortar, and sequentially carrying out pouring molding, curing and demolding on the mortar to obtain the impervious concrete prefabricated part. According to the invention, a plurality of mineral components are compounded, and the grain composition of the aggregate and the cementing material is optimized, so that the prepared concrete prefabricated component has excellent waterproof and anti-permeability performances.
本申请涉及混凝土技术领域，具体公开了一种抗渗混凝土预制构件及其制备工艺。其技术要点是：一种抗渗混凝土预制构件，包括如下重量份数的组分：砂800‑1000份、碎石800‑1000份、水泥400‑450份、矿粉80‑120份、粉煤灰100‑150份、羟丙基甲基纤维素10‑15份、碳化稻壳灰100‑150份、水200‑250份。其制备工艺为：将砂、碎石、水泥、矿粉、粉煤灰、羟丙基甲基纤维素、碳化稻壳灰、水搅拌混合后，得到砂浆，将砂浆依次进行浇筑成型、养护、脱模，即得防渗混凝土预制构件。本申请通过采用多种矿物组分复配，优化骨料和胶凝材料颗粒级配，所制备的混凝土预制构件，具有优异的防水、抗渗性能。
