Cas 569 61 9 Construction Chemical Additives Sika For Cementitious Mortars

Product Description

Water-reducing admixtures work by dispersing the cement particles more efficiently, reducing the surface tension of the water, or a combination of both mechanisms.

Water-Reducing Admixture can be classified into two main types: lignosulfonates and polycarboxylates.

Lignosulfonate-based water reducers are derived from wood pulp and are one of the earliest types of water-reducing admixtures.

Water-Reducing Admixtures are effective in reducing the water content and improving workability. However, they have limitations in terms of dosage rates and compatibility with certain types of cement.

Features:

• Product Name: Water-Reducing Admixture
• Appearance: White powder
• Workability enhancement: Water-reducing admixtures improve the workability of concrete by dispersing cement particles more efficiently and reducing the surface tension of water. This results in improved flow, reduced segregation, and enhanced cohesiveness of the concrete mixture.
• Workability enhancement: Water-reducing admixtures improve the workability of concrete by dispersing cement particles more efficiently and reducing the surface tension of water. This results in improved flow, reduced segregation, and enhanced cohesiveness of the concrete mixture.

Applications:

Water-reducing admixture is a chemical additive used in concrete and grout to reduce the amount of moisture in concrete while maintaining its flowability. Water reducing agents are widely used in the construction and engineering industries, and their main uses include the following aspects:

Improve the fluidity of concrete: Water reducing agents can reduce the surface tension of concrete and improve its fluidity and pumpability. This is important to construction crews as it makes it easier to pour, distribute the concrete evenly and fill the formwork, making the job more efficient.

Save water: Using water reducing agents can reduce the water requirements of concrete. Since the water-reducing agent can effectively reduce the water-cement ratio, the amount of water required during the construction process is reduced accordingly. This helps conserve water, especially in arid areas or places where water is scarce.

Control setting time: Water reducing agents can also regulate the setting time of concrete. By using different types of superplasticizers, the setting time of concrete can be extended or accelerated to suit specific construction needs. This is especially important for large engineering projects or construction where weather factors are a concern.
