Description

Technical field

[0001] The present invention is the field of concrete exterior preparation, which involves a high -performance water reducing agent and preparation method of normal temperature synthetic polycarboxylic acid system. Background technique

[0002] The concrete exterior agent is a material added before or during the concrete mixing or during the mixing process to improve the performance of new mixing and hardening concrete. It is characterized by a small amount and a large effect.The application of various concrete exterior agents has improved the many properties of new mixing and hardening concrete, promoted the development of new concrete technology, expanded the application of industrial by -products in glue materials, and help saves resources and environmental protection. It has gradually become high -quality high -qualityThe component of concrete is indispensable.

[0003] Around 2000, my country's concrete engineering community gradually realized the high -perfo...
