Selecting optimized mix proportion of bagasse ash blended high performance concrete using analytical hierarchy process (AHP)

Apart from strength properties, durability, toughness and workability are also important criteria in defining the performance of a concrete structure. Hence \"High Performance Concrete (HPC)\" is introduced. It is different from high strength concrete and can have various applications. In this paper, the properties (Mechanical and Durability) of High Performance Concrete blended with bagasse ash at 5%, 10%, 15% and 20% are studied. However, it is difficult to analyze the performance based on different properties obtained from different experiments. Hence it is necessary to combine all the criteria/properties into a single value to obtain a result by a technique called Analytical Hierarchy Process (AHP).It is an effective tool for dealing with complex decision making, and may aid the decision maker to set priorities and make the best decision. In addition, the AHP incorporates a useful technique for checking the consistency of the decision maker\'s evaluations, thus reducing the bias in the decision making process.
