Abstract

The invention relates to the technology of concrete admixtures, and provides an efficient water-reducing agent and a preparation method thereof. The efficient water-reducing agent is prepared from the following raw materials in parts by weight: 100 parts of prenyl alcohol polyoxyethylene ether, 0.8-1.2 parts of hydrogen peroxide, 0.14-0.19 part of thioglycollic acid, 6-9 parts of acrylic acid, 0.06-0.20 part of ascorbic acid and 173-247 parts of water. According to the preparation method, the preparation condition can be fulfilled only by simply regulating the temperature, and the preparation process is simple and convenient to implement; and the prepared efficient water-reducing agent is in accordance with construction requirements.

Description

technical field [0001] The invention relates to the technical field of water reducers, in particular to a high-efficiency water reducer and a preparation method thereof. Background technique [0002] Concrete is a widely used material in civil engineering, construction, water conservancy, high-speed railway and highway projects. The newly built concrete batching plants in major cities in China can provide stable and high-quality concrete, which will undoubtedly speed up the construction progress and Improve project quality. The increase in the demand for concrete has promoted the development of concrete admixture technology. Concrete admixtures have become an indispensable and important component in concrete. They play a central role in concrete production technology and are the key to determining the quality of concrete. [0003] Water reducer refers to an admixture that can reduce mixing water consumption and increase concrete strength under the condition of constant work...
