Synergistic binder-reducing concrete admixture and preparation method thereof
The invention relates to the technical field of binder-reducing concrete admixtures, and discloses a synergistic binder-reducing concrete admixture and a preparation method thereof. The synergistic binder-reducing concrete admixture comprises a polycarboxylic acid water reducer, a polycarboxylic acid slump retaining agent, a binder reducing agent, an air entraining agent, a defoaming agent, a water-retaining agent, a retarder, a pH regulator and water. The invention further provides the preparation method of the synergistic binder-reducing concrete admixture. The synergistic binder-reducing concrete has the double effects of reducing a binder and reducing water, and can play a role in dispersing a binding material in concrete to the greatest extent, so the binding material which only plays a filling role originally is fully hydrated, and the strength and the working performance of the concrete are improved; the problem that an admixture storage tank and a binder reducing agent storage tank need to be prepared at the same time in a mixing plant is solved, the problem that the quality of the mixing plant fluctuates due to inaccurate weighing of the binder reducing agent is solved, the mixing plant can well adapt to changes of various materials, and concrete quality fluctuation caused by the changes is avoided.
本发明涉及涉及减胶混泥土外加剂的技术领域，公开了一种增效减胶型混凝土外加剂及其制备方法，包括聚羧酸减水剂，聚羧酸保塌剂，减胶剂，引气剂，消泡剂，保水剂，缓凝剂，PH调节剂，水以及其制备方法；本发明拥有减胶和减水双重效果，可以最大可能的对混凝土中的胶凝材料起到分散作用，使原本只起到填充作用的胶凝材料充分水化，以此提高混凝土的强度和工作性能；解决了搅拌站需要同时准备外加剂储罐和减胶剂储罐的问题，解决了搅拌站因为减胶剂称量不准而导致质量波动的问题，还可以良好的适应各种材料的变化，避免了因此而产生的混凝土质量波动。
