Evaluation of compressive strength of concrete in bipolar fuzzy environment

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