Evaluation of compressive strength of concrete in bipolar fuzzy environment

Abstract

Concrete is the most widely used building material. Numerous varieties of concrete are available. They are resolved by the formation of binders and the types of aggregate used to suit the application of the engineered material. The quality of the concrete is based on the specific proportions of different materials added to it such cement, slag, ash, water, superplasticizer, coarse aggregate and fine aggregate. The compressive strength of concrete hangs on many factors such as water-cement ratio, cement strength, quality of concrete material during making of concrete which is determined using MCDM methods. In this paper COPRAS and WASPAS methods are used to determine the ranking order of various set of concrete mixtures produced in the laboratory.
