Fuzzy Logic Model to Estimate the Compressive Strength of 7 days old Concrete Mixture

Concrete mix design is a process of proportioning the ingredients in right proportions. Though it is based on sound technical principles and heuristics, the entire process is not in the realm of science and precise mathematical calculations. This is because of impreciseness, vagueness, approximations and tolerances involved. This paper presents the development of a novel technique for approximate proportioning of standard 7 days old concrete mixes. The aim of this study is to design a Fuzzy Logic model for determination of the compressive strength of a concrete. The datasets which has been loadedinto Fuzzy Logic model contains 126concrete mixtures. Input fields of the fuzzy expert system are weight percent ofcement, water, blast furnace slag, fly ash, super plasticizer, fine aggregateand coarse aggregate. Output field is concrete compressive strength. Finally, 110 rules used for this Fuzzy Logic modeling
