Admixtures are the elements other than water, aggregates and cement used for making concrete. Generally, concrete admixtures are used to improve the behavior of concrete under a variety of weather conditions as well as to reduce the cost of concrete construction.
Why Concrete Admixtures are Important?
The use of admixtures is increasing. Chemical manufacturers in UAE say that it is because of the physical as well as economic benefits it provides. Admixtures benefits the concrete in the following ways:- Reduces the water consumption of concrete.
- Reduces the concrete shrinkage and slump loss.
- Prevents steel corrosion and reduce chloride ion diffusion.
- Reduce the cost of concrete
- Admixtures reduce the required quantity of cement and makes the concrete more economical.
- Achieves certain properties in concrete more effectively compared to other means.
- Maintains the quality of concrete during the mixing, transporting, placing, and the curing process in extreme weather conditions.
Types of High-Performance Corromix Admixtures
- Water-reducing admixtures generally decreases the required amount of water for a concrete mixture for about 5 to 10 percent. Therefore, any concrete construction that contains water-reducing admixture needs less water in achieving the required slump, which results in a lower water-cement ratio.
- Accelerating admixtures usually increase the rate of early strength development of concrete. It lessens the time required for the proper curing and protection, and accelerates the start of finishing operations. This type of admixture is especially beneficial in modifying the properties of concrete in cold weather.
- Superplasticizers is also known as High-Range Water Reducers (HRWR). The use of this admixture often results in substantial enhancement in workability, reduction of water content by 12% to 30% may be achieved using superplasticizers.
- Retarding admixtures are known in slowing down the setting rate of concrete. They are also used to counteract the accelerating result of hot weather on concrete setting. Moreover, retarders admixtures keep the concrete workable during placement and postpone the initial set of concrete.
