Common Concrete Admixture Types And Their Overview

With the continuous development of the concrete market, the application of admixtures is becoming more and more extensive, and different types of admixture products play different roles in it. So, what are the functions of these admixtures?

The knowledge and understanding of testing by engineering and technical personnel is based on the understanding of naphthalene series water reducing agents.

Since the main samples used in the formulation of the previous version of the specification were naphthyl water-reducing admixtures, this shows that most of the test methods currently used can accurately reflect the true performance of naphthyl water-reducing admixtures. The performance deviation of other different parent water-reducing agents was also compared using naphthalene-based water-reducing agents as a reference. Therefore, commonly used admixture acceptance methods, such as slurry fluidity and adaptability, mortar water reduction rate, etc., for pure naphthalene-based water reducing agents, the detected data have a strong correlation with concrete. Only based on the corresponding relationship can the specific application effect be truly reflected.

As the latest third-generation water-reducing agent, polycarboxylate superplasticizer water-reducing agent is much better than the second-generation water-reducing agent in terms of water reduction rate and durability. And because its production and use are green and environmentally friendly, it has no side effects on concrete. Small, representing the future development direction of concrete admixtures.

Jufu Chemical's polycarboxylate superplasticizer water-reducing agent has much better adaptability to cement than the second-generation water-reducing agent. However, because it is much more sensitive to materials than superplasticizers and is easily adsorbed by mud powder, and the adsorption capacity of polycarboxylic acid to different types of soil varies greatly, technicians still have certain technical deficiencies. Learn about polycarboxylic acids. The scope of use is still relatively limited. In the past few years, it was only used in important projects or when concrete performance requirements were high. With the improvement of construction quality requirements, the country's emphasis on environmental protection and the greening process of concrete enterprises, polycarboxylic acid admixtures have multiple advantages in terms of performance and environmental protection, and are used in the construction and management of some big cities - Related project. Good companies began to gradually promote it.
