High-durability recycled concrete and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses high-durability recycled concrete and a preparation method thereof. The high-durability recycled concrete comprises the following components in parts by mass: 100 parts of water; 320 to 330 parts of cement; 26 to 30 parts of fly ash; 910 to 925 parts of recycled aggregate; 210 to 220 parts of modified stone powder; 6.3 to 6.5 parts of an additive; the modified stone powder is prepared by soaking and modifying stone powder in a modification solution; the modified liquid is a compound of water, fatty alcohol polyoxyethylene ether sodium sulfate, alkyl glycoside and barium petroleum sulfonate. The method has the advantage of improving the durability of the concrete doped with a large amount of recycled aggregate.
本发明涉及混凝土技术领域，具体公开了一种高耐久性再生混凝土及其制备方法。高耐久性再生混凝土，包括以下质量份数的组分：水100份；水泥320‑330份；粉煤灰26‑30份；再生骨料910‑925份；改性石粉210‑220份；外加剂6.3‑6.5份；改性石粉通过石粉在改性液中浸泡改性制得；改性液为水、脂肪醇聚氧乙烯醚硫酸钠、烷基糖苷、石油磺酸钡的复配。本发明具有提高大量掺用再生骨料的混凝土的耐久性的优点。
