Why should a water reducer be added when mixing concrete in a mixing plant?
The concrete mixing plant usually uses stones, large sand, cement, fly ash, etc., as well as indispensable water.
So what is a water-reducing agent? As the name implies, a water-reducing agent is a “medicine” that can reduce water consumption. In other words, the amount of water is reduced, so don’t other materials use more? Among these ingredients such as aggregates and powders, water is the cheapest, so why reduce the amount of water?
Concrete mixing, in layman’s terms, is mixed with mud. If there is too much water, the mud will be thin, and if it is sticky, it will easily cause brittle cracking and fall off.
With the development of highways, high-speed railways and other technologies, the requirements for concrete strength in engineering are getting higher and higher. We need concrete that can move, but also has high strength and strong adhesion. What should we do? Water reducers come in handy.
The water reducing agent can reduce the amount of water in the concrete mixing process without reducing the activity of the concrete, and the firmness and viscosity of the concrete are not reduced.
