Evaluation of Compressive Strength of Concrete for Aci, Isi & Doe Mix Design Methods

Abstract

Different concrete mixes are aimed at achieving desired properties of workability, durability, strength, etc. In order produce a concrete mix with proper pre-defined characteristics in fresh and hardened state, it is very essential to have a proper mix design which leads to selection and proportioning of constituents. The concrete mix design methods of American Concrete Institute (ACI-USA), Indian Standards Institution (ISI-India), Department of Environment (DOE-UK) are built on the same principles and their empirical relation are framed after various experiments made on locally available material. This report gives the variation of compressive strength of concrete for the various mix designs of ACI, ISI& DOE methods. The compressive strength of concrete for 14 days and 28 days curing is tested in a defined size of concrete cube and the reading are tabulated for the above stated mix designs. This report also gives the design calculation required for the various mix methods and compares the experimental results.
