Composite water reducing agent for machine-made sand concrete and preparation method of composite water reducing agent
The invention relates to the field of concrete admixtures, in particular to a composite water reducing agent for machine-made sand concrete and a preparation method of the composite water reducing agent, and aims to solve the problems that an existing water reducing agent is not ideal enough in water reducing effect and poor in adaptability to cement, the quality and construction efficiency of concrete are affected, and application of machine-made sand in higher-performance concrete is limited. According to the composite water reducing agent for the machine-made sand concrete, the water consumption of the machine-made sand concrete can be remarkably reduced through an optimized chemical component ratio and a preparation process, an excellent water reducing effect is achieved, the flowability and working performance of the machine-made sand concrete can be remarkably improved, the hydration effect of the machine-made sand concrete can be improved, and the service life of the machine-made sand concrete is prolonged. The uniform distribution of the internal structure of the machine-made sand concrete is promoted, so that the water-retaining property, the flowability and the pumpability of the machine-made sand concrete are improved, the water-binder ratio is reduced, the early-stage and later-stage strength of the machine-made sand concrete is enhanced, and the durability of the machine-made sand concrete is remarkably improved.
本发明涉及混凝土外加剂领域，具体涉及一种机制砂混凝土用复合减水剂及其制备方法，用于解决现有的减水剂减水效果不够理想、与水泥适应性差，影响了混凝土的质量和施工效率，这限制了机制砂在更高性能混凝土中的应用的问题；该机制砂混凝土用复合减水剂通过优化的化学成分比例与制备工艺，能够显著降低机制砂混凝土的用水量，具有优异的减水效果，能显著提高机制砂混凝土的流动性和工作性能，能改善机制砂混凝土的水化效果，促进机制砂混凝土内部结构的均匀分布，从而提高了机制砂混凝土的保水性、流动性和可泵送性，降低了水胶比，增强了机制砂混凝土的早期和后期强度，显著提升其耐久性。
