Abstract

Concrete has been the major instrument for providing stable, reliable Infrastructure .Deterioration, long term poor performance and inadequate resistance to hostile environment coupled with greater demands for more sophisticated architectural form, led to research into the micro structures of cements and concretes and more elaborate codes and standards. Modification in cement concrete to improve its strength and durability is need of the hour. Drawbacks of cement concrete such as low tensile strength, susceptibility to chemical attack, corrosion of reinforcement and low durability have to be overcome. An attempt is made in the present work to investigate the influence of this admixture on the compressive strength of concrete. The experimental study of this investigation consists of concrete mix for target mean strength. The mix was worked out giving certain proportions by keeping the obtained water-cement ratio constant. The mix is obtained with water cement ratio 0.3. For this mix the different percentages of admixtures was added i.e., 5%, 10%, 15% by weight of cement. These percentages were added in cement mortar 1:3 ratio, specimens were tested up to failure o study the behavior in compression and tension.
