Concrete workability regulator as well as preparation method and application thereof

GU JINLONG

The invention provides a concrete workability regulator as well as a preparation method and application thereof, and belongs to the technical field of concrete admixtures. According to the invention, fatty alcohol-polyoxyethylene ether, polyvinyl alcohol, sodium acetate and modified starch are matched for use, so that the workability state of the concrete can be improved, but the strength and fluidity of the concrete can be reduced; by adopting the reinforcing agent, the strength of the concrete can be improved to a certain extent on the basis of counteracting the influence of the fatty alcohol-polyoxyethylene ether, the polyvinyl alcohol, the sodium acetate and the modified starch on the strength of the concrete; the formic acid is adopted, so that the influence of the fatty alcohol-polyoxyethylene ether, the polyvinyl alcohol, the sodium acetate and the modified starch on the fluidity of the concrete can be counteracted, and the concrete is kept in a relatively good working state.

本发明提供了一种混凝土和易性调节剂及其制备方法和应用，属于混凝土外加剂技术领域。在本发明中，所述脂肪醇聚氧乙烯醚、聚乙烯醇、乙酸钠以及改性淀粉配合使用，能够提高混凝土和易性状态，但会使混凝土的强度以及流动度有所下降，本发明采用增强剂在可以抵消添加脂肪醇聚氧乙烯醚、聚乙烯醇、乙酸钠以及改性淀粉对混凝土强度影响的基础上，还能够一定程度上提高混凝土的强度，采用甲酸可以抵消添加脂肪醇聚氧乙烯醚、聚乙烯醇、乙酸钠以及改性淀粉对混凝土流动度的影响，使混凝土保持较好的工作状态。
