But using HSC cost us more. Alternately we can use some admixtures which can increase strength indirectly. In this paper we have used GGBS, Fly ash and SP-430 Super plasticizers. On conducting different trail mixes we have come to know that by using 10% of fly ash, 30% of GGBS & 60% of Cement leads us to 10.3% raise in compressive strength for 28 days and 30.8 % for 180 days. Key words: compressive strength, Fly ash, GGBS, High strength concrete, super plasticizers.

INTRODUCTION The misfortune in the wellbeing of recently developed solid structures provoked the most immediate and certain proof of the keep going two/three decades on the service life execution of our construction and the subsequent test that stands up to us is the disturbing and inadmissible rate at which our infrastructure everywhere throughout the world are experiencing decay when presented to real environments. The Ordinary Portland Cement (OPC) is one of the main ingredients used for the production of concrete and has no alternative in the civil construction industry. Tragically, in the creation of concrete includes emanation of a lot of carbon-dioxide gas into the air, a noteworthy commitment for green house impact and the worldwide warming .Hence it is
