Concrete Superplasticizer & Plasticizer
Admixtures are chemicals in the form of powder or liquid which are added to the concrete during the mixing process, at the plant or inside the transit mixer, prior to casting, in order to improve certain properties of the concrete or to add properties which are not present in regular concrete. Basically, concrete admixtures are divided into two groups: Plasticizers, and superplasticizers, the main difference between them being the extent of the admixture's ability to reduce the quantity of water required, whilst maintaining or even improving the concrete's workability. In general, the difference between the two types can be defined as follows: The plasticizer can reduce up to 10% of the water required in the mix whilst maintaining the concrete's workability, while the superplasticizer can reduce 20% and more of the water quantity.
