Effect of Chemical Admixtures on the Performance of Strength of Cement Mortar Cubes
Keywords:
Admixture, Strength, PerformanceAbstract
To increase the strength and stability of concrete, chemicals and admixtures play a important role in modifying the desired properties in any design mix. The development of these admixtures in their performance contributed a lot to the modern concrete over the conventional concrete. In the present study, effect of admixtures is considered to evaluate their performance on strength with their respective optimum dosages. Cement mortar cubes tested for 3 days, 7 days and28 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.
