Abstract
Admixtures are chemical additives in concrete and play a vital role in modifying the desired properties in fresh concrete or green concrete. The evolution of these admixtures in their performance contributed a lot to the modern concrete over the conventional concrete. In the present experimental study, effect of low, medium and high end admixtures is considered to evaluate their performance on strength with their respective optimum dosages. Cement mortar cubes tested for 3 days, 7 days and 28 days with standard water–cement ratio determined from the standard consistency test of cement paste following IS procedures reveal notable improvements in the strength. This study highlights the minimum water–cement ratio required in each category of the admixture, and its effect on strength is discussed.
