What are the factors that affect the effectiveness of water reducing agents?

Water reducing agent is one type of additives that is widely used in concrete/dry mixed mortar. Its effect is very important. Generally, there are three main factors that affect the effect of water reducing agent.

The influence of cement characteristics

Different types of cement will have an impact on the effect of the water-reducing agent. The mineral composition and chemical composition of the cement clinker and the form of gypsum (as a setting regulator) will all affect the effect of the water-reducing agent. In addition, the fineness of the cement, the type and amount of admixtures in the cement, the freshness of the cement, the moisture content and temperature of the cement, etc. will also affect the effect of the water-reducing agent.

The influence of the characteristics of the water-reducing agent

Different water-reducing agents have different characteristics and are suitable for concrete of different strengths. When using them, you should choose the appropriate water-reducing agent according to your needs, otherwise the effect of the water-reducing agent will be affected.

During storage and use, some problems are often encountered, which make the concrete water-reducing agent less effective or even invalid. The main reasons are:

• Rainwater enters the water reducing agent tank, causing the concentration to decrease
