Admixture

Durability and high strength characteristics make concrete more popular in the infrastructure arena.

Concrete technology gives an important ingredient known as admixture which enhances concrete properties. Chemical admixtures are components in concrete that are added to the mix just before or during mixing, with portland cement, water, sand, aggregate, fibre, and additives.It improves quality performance like workability, durability, strength, and finishing quality of concrete.

Why Admixtures is required?

The construction of concrete structures is a never-ending process. The demand for building materials is increasing as new infrastructure technologies are developing with more invention. Time plays a very significant role throughout the construction process. Admixtures help to save energy, cost, and time to achieve construction goals without compromising quality.

Producers use admixtures primarily to

• reduce the cost of concrete construction;
• modify the properties of hardened concrete;
• ensure the concrete’s quality during mixing, transporting, placing, and curing;
• overcome certain emergencies during concrete operations.

The use of suitable batching and concreting processes is critical to the successful usage of admixtures. These are delivered in liquid form and are mixed into the concrete at the plant. The kind and amount of cement used, as well as the water content, mixing time, slump, and concrete and air temperatures, all influence the effectiveness of an admixture.

Silkon has a comprehensive selection of concrete admixtures with creative choices for concrete mix design, whether it’s to reduce the water content of a mix, use a more cost-effective mix design, or achieve enough early strength. Concrete admixtures from Silkon can help you fulfill the demands of current concrete technology and the building industry.

Silkon’sSupermix Series are used to improve the various characteristics of the concrete as:

• Protect Against Freeze-Thaw Cycles to Improve concrete Durability and resistance against severe frost weather conditions.
• Water Reduction in the Mix, i.e., minimise water-cement ratio to achieve the desired slump.
• Mid-Range water reducers
• High-Range water reducers superplasticizers
• High Compressive Strength Concrete
• Corrosion Protection by decreasing permeability
• Set Acceleration
  • To enhance the rate of early strength in concrete which allow us to remove the formwork earlier and the curing time is reduced. Recommended usingwhere concreting is carried out in cold weather.
• Set Retardation
  • To delay or to slow down the chemical process of hydration,which helps concrete to remains plastic and workable for a longer time than normal concrete. Recommendedusing where concreting is carried out in hot weather.
• Crack Control (shrinkage reduction)
• Self-Compacting Concrete
  • Fast placement without mechanical consolidation.
  • Minimises voids in highly-reinforced areas and eliminates problems associated with concrete vibration.
• PQC Concrete
• Finish Enhancement
• Improve the performance of Cement replacements like Flyash, GGBFS, Micro Silica, Metakaolin, etc.
• Maintain concrete quality during the mixing, transport, installation, and curing processes in inclement weather or in the event of an emergency during concrete operations.
• All value-added concrete.
