The invention belongs to the technical field of additives for building concrete, and particularly relates to a catalyst, a water reducing agent with a low acid-ether ratio, a preparation method of the water reducing agent and application of the water reducing agent in concrete. The water reducing agent provided by the invention has a compound shown in the following formula (I): the water reducing agent prepared by the invention has good performance in cement dispersion and concrete application due to high conversion rate, and an effective means is provided for solving the problem of application of the water reducing agent in concrete. The concrete mixed by a common water reducing agent has the phenomena of bleeding, slurry bleeding, high concrete viscosity and bottom digging, while the concrete mixed by the water reducing agent prepared by the invention is relatively soft, the wrapping property is improved, the pumpability and the comprehensive performance of the concrete are improved, and the concrete has remarkable advantages in industrial application.
本发明属于建筑混凝土用添加剂技术领域，具体涉及一种催化剂、低酸醚比减水剂及其制备方法和在混凝土中的应用。本发明的减水剂具有如下式(I)所示的化合物：本发明制备的减水剂因转化率高，在水泥分散和混凝土应用上有很好的性能表现，为解决减水剂在混凝土的应用提供了有效手段。普通减水剂拌制的混凝土会出现泌水泌浆、混凝土粘度大、扒底现象，而本发明制备的减水剂拌制的混凝土，混凝土较为松软，包裹性提高，提升了混凝土的可泵性和综合性能，在产业应用上取得了显著的优势。
