Concrete Mix Theories (Comparative Study between IS Code and ACI Code)

With the development of concrete technology and through the growing number of tall building structures, the use of higher strength concrete is becoming more popular. High strength concrete has grown quite attractive to civil engineers and substantial scientists as it displays advanced workability, superior mechanical properties and improved durability. High strength concrete (HSC) has been progressively used in the structures like tall buildings, flyovers, bridges and offshore structures. In (India) as well in our state (J&K) the use of HSC is gaining importance, for example M45 grade of concrete has been utilized in Jahangir Chowk-Rambagh flyover. Now the problem lies in the mix design of concrete by nearby obtainable materials. As mix design is a method of stipulating the combination of constituents mandatory to come across expected properties of fresh and hardened concrete. Concrete mix design is a well-established exercise round the globe. Wholly advanced countries, in addition to numerous emergent countries, have established their concrete mix design method an acute assessment of mix design approaches have been approved out for M40 grade of concrete using American Concrete Institute (ACI) and Bureau of Indian Standards (BIS) methods to find the resemblances and alterations between the two design theories. The scope of our study is to compare ACI and IS recommended mix design guidelines for High Strength Concrete (M40). The purposes of the study is to develop concrete of grade M40 using native materials under local environmental conditions using IS and ACI methods.
