Plastic-retaining anti-freezing magnesium concrete anti-cracking agent and preparation method thereof
The invention discloses a plastic-retaining anti-freezing magnesium concrete anti-cracking agent and a preparation method thereof. The plastic-retaining anti-freezing magnesium concrete anti-cracking agent is prepared from the following raw materials in percentage by mass: 40-60% of a modified magnesium oxide expanding agent, 10-30% of superfine limestone powder, 15-25% of a plastic-retaining component and 3-13% of an anti-freezing component. The plastic-retaining anti-freezing magnesium concrete anti-cracking agent disclosed by the invention has multiple effects of compensating concrete cracks, reducing slump loss of fresh concrete and continuously exerting expansion efficiency in a low-temperature environment. The preparation method is simple and can be used for industrial production.
本发明公开了一种保塑防冻型镁质混凝土抗裂剂及其制备方法。该保塑防冻型镁质混凝土抗裂剂，其由如下质量百分比的原料制成：改性氧化镁膨胀剂40～60％、超细石灰石粉10～30％、保塑组分15～25％、防冻组分3～13％。本发明的保塑防冻型镁质混凝土抗裂剂具有补偿混凝土裂缝、减小新拌混凝土坍落度损失、在低温环境下持续发挥膨胀效能的多重作用。本发明的制备方法简单，可工业化生产。
