Concrete Admixture: What is It? 

A concrete admixture is used to optimize the pre-existing concrete mix. It works as an added benefit or property to make it better suited to the project. The substance is usually added directly before or during the mixing process, and one can find various types of chemical admixtures in industry.  

Different Kinds of Admixtures 

Here, as a concrete admixture manufacturer, we at Vinati Organics will note down the various types of chemical admixtures and their potential uses so that you can better understand how they can make your concrete stand out among all.  

  • Water reducing admixtures 
  • Accelerating admixtures  
  • Superplasticizers 
  • Air entrainment admixtures  
  • Shrinkage reducing admixtures 
  • Set retarding admixtures 

Water Reducing Admixtures  

These chemical admixtures are used to achieve the desired concrete strength with the help of a much lower water-cement ratio. By considering less cement in the concrete mix, the CO2 emissions will lessen, and an overall energy usage rate per concrete batch will become a part of the production.  

Accelerating Admixtures  

Accelerating admixtures reduces the time taken for concrete to set fully, thus speeding the rate at which concrete strengthens over time. The critical component in most of these admixtures is calcium chloride, and it is applied in scenarios where the weather becomes highly volatile to damage the site or when the project is running on a tight schedule. 


These are primarily used to produce flowing concrete. As a concrete pouring form, Superplasticizers define highly workable concrete that is strong and applied to closely spaced reinforced steel and thin section placements for added durability.  

Air Entrainment Admixtures 

These chemical admixtures are meant to increase the freeze-thaw durability of concrete. Air entrainment is often desired, where the concrete experiences more freeze-thaw cycles. However, the numerous benefits of this admixture include a high range of workability and durability, proving to be one of the best and most versatile concrete admixtures.  

Shrinkage Reducing Admixtures  

As a concrete admixture manufacturer, we explain shrinkage-reducing admixtures as additives that reduce the act of shrinkage during the drying process. To avoid shrinkage cracking, these chemical admixtures are used to minimize structural problems ahead. 

Additionally, one must remember that these admixtures can lessen the strength of the development process during the early and later stages of concrete curing.  

Set Retarding Admixtures  

These work as the opposite of accelerating admixtures. They are known to delay the chemical reaction that allows the setting process to begin. The main reason to delay this process is to offset how higher outdoor temperatures can rush the curing process. For projects to complete during sweltering summers, set retarding admixtures can be of great help.
