Water is needed while working with concrete to improve workability and flow. On the other hand, excessive water content can weaken concrete and increase its susceptibility to shrinkage and cracks. So, a kind of admixture called plasticizer admixture is used to strengthen and prolong the life of concrete while using less water. Water-reducing admixtures, often known as plasticizers, aid in lowering a concrete mixture’s water content by roughly 5 to 10%.
Admixtures that are similar to plasticizers are called superplasticizer admixtures, or high-grade water reducers. It is added to concrete to help decrease its water content by 12% to as much as 30% and to make the concrete more workable. Low-slump, stiff concrete is much improved with this kind of additive, making it more pourable and fluid. Additionally, they assist strengthen concrete by lowering shrinkage in it.
Water-soluble polymer molecules make up superplasticizers. These molecules absorb the cement grain surface when combined with concrete, contributing to the formation of an ionic group. Because of this, the cement particles have a negative charge, which leads to steric hindrance and mutual repulsion (a restriction on intra- or intermolecular contact brought on by a molecule’s spatial structure).
