Concrete additives or admixtures are chemicals in the form of powder or fluids that are added to the concrete to give it certain characteristics which is not obtainable with plain concrete mixes. In normal use, admixture dosages are less than 5% by mass of cement and are added to the concrete at the time of batching/mixing. The common types of admixtures we manufactur are as follows:
Superplasticizer : Superplasticizer (also called high-range water-reducers) are a class of plasticizers that have less harmful effects and can be used to increase workability more than is practical with traditional plasticizers like lignosulfonates.
Foaming Agent : Also known as air entraining agent. Air entrainments add and entrain tiny air bubbles in the concrete, which reduces damage during freez-thaw cycles, increases durability. However, entrained air entails a trade off with strength, as each 1% of air may decrease compressive strength 5% , hence is used to produce light weight concrete and insulating concrete.
Organo Accelerator : Accelerators speed up the hydration (hardening) of the concrete.
SMF Powder : Sulfonated melamine formaldehyde is a superplasticizer in powdered form.
