Problems solved by technology
[0008] The present invention is sensitive to the dosage of existing thickeners, which can easily lead to excessive slurry viscosity and poor fluidity. The strength of existing air-entraining agents is reduced due to the improper introduction of bubble structures. The existing multi-functional water reducing agent

Abstract
The invention provides a workability regulator with a water reducing function. The workability regulator comprises components as follows: workability regulation macromolecules and water, wherein the workability regulation macromolecules are prepared through copolymerization; comonomers contain polymerization-activity-end microhydrophobic modified polyether and sodium alpha-olefin sulfonate; according to the workability regulator with the water reducing function, small and stable bubbles can be introduced effectively, and saline-alkaline resistance is excellent.
Description
technical field [0001] The invention belongs to the technical field of building materials, in particular to the technical field of concrete admixtures, in particular to a concrete workability regulator with water-reducing function and a preparation method thereof. Background technique [0002] High-performance concrete (HPC) was officially proposed by the United States in 1990. It refers to concrete with high durability, high strength and high fluidity. It is another major progress after high-strength concrete and is the leading direction of concrete development today. One The important content is to require fresh concrete to have high workability. Improving the workability of concrete is the key to improving the workability of fresh concrete. Among the various method theories proposed, adding admixtures to improve the workability of concrete mixtures is considered to be a simple, effective and feasible method. [0003] As we all know, there are three main admixtures to im...
