Water reducing agent and preparation method and application thereof
The invention provides a water reducing agent as well as a preparation method and application thereof. The invention relates to the technical field of concrete admixtures. The water reducing agent ismainly prepared from polycarboxylic acid, a defoaming component, an air entraining component, a water retention component, a retarding component and water according to a specific content ratio. The raw materials are reasonably matched with one another so as to realize the synergistic effect; according to the present invention, with the application of the prepared water reducing agent in the machine-made sand-containing concrete, the workability, the wrapping property and the pumping property of the machine-made sand-containing concrete can be improved, and the strength of the machine-made sand-containing concrete can be improved so as to effectively alleviate the problem that the application effect of the existing water reducing agent in the machine-made sand-containing concrete is not ideal.
本发明提供了一种减水剂及其制备方法和应用，涉及混凝土外加剂技术领域，所述减水剂主要由聚羧酸、消泡组分、引气组分、保水组分、缓凝组分和水经特定含量配比得到，上述原料通过各组分之间的合理配伍，能够实现协同增效的作用，将制得的减水剂应用于含机制砂混凝土中，能够改善含机制砂混凝土的和易性、包裹性和泵送性，并提高含机制砂混凝土的强度，进而有效缓解了现有减水剂在含有机制砂的混凝土中的应用效果并不理想的问题。
