As a new generation of water reducing agent, polycarboxylic acid water reducing agent is widely used in concrete engineering, but there are still some problems in the process of use that are difficult and difficult to solve. Therefore, some matters should be brought to our attention during use.

In the past 40 years, the application of water-reducing agents in concrete has developed rapidly. As a new generation of water-reducing agents, polycarboxylic acid-based water-reducing agents have become an essential component for the preparation of high-performance concrete.

Cement is an indispensable basic raw material in the construction of national infrastructure and economic development. However, with the increasing pollution of the environment, the production of cement is still in a high energy consumption industry.Portland mineral cement is widely used in the market.

Polyethylene glycol (PEG) is very common and useful in various industries. It mainly neutralizes the acidity of fillers in rubber, accelerates the vulcanization rate and crosslinking density, has good water solubility, and has many organic components. Good compatibility, with excellent lubricity, moisturizing and dispersing properties. Generally, PEG-4000 is used in the rubber, because the molecular weight of 4000 is solid flake, easy to process, easy to add, difficult to precipitate, and the polymer with medium molecular weight has better compatibility with rubber.

Over the years, defoamers have developed continuously and gradually entered all walks of life. In industrial production involving stirring, defoamers are needed for eliminating and suppressing harmful bubbles. The generation of harmful bubbles will not only affect the quality and appearance of products, but also cause the unreasonable use of resources and increase the construction cycle. The harmful air bubbles produced during concrete mixing can cause material defects. The use of defoamer can optimize the structure of concrete holes, make the appearance of concrete without honeycomb surface, improve the mechanical properties of concrete materials and prolong the service life of concrete materials. This shows that the control and elimination of harmful foam has great technical and economic significance.

The Triisopropanolamine,Diethanolisopropanolamine,Triethanolamine as cement grining aid could effective participate in hydration reaction with , C3A, C3S, C2S, and C4AF.

1. Mix Ratio AdjustmentAccording to the construction environment, the summer construction mix proportion should be adjusted reasonably. In order to reduce the loss of concrete slump and avoid the concentration of hydration heat, the cement with lower hydration heat can be used as raw materials, and
