Concrete mix design program3/7/2024 Mix design performed using optimization techniques like GA proved to be efficient when compared to mix design using manual approach. This resulted in about 6-10 percent reduction in quantities of cement for various cases of mix design considered in the study. The study results indicated that quantities of cement have been reduced by about 25-40 kg per cubic meter through mix design using GA technique. It is observed that the use of Genetic Algorithms resulted in economical mix by minimizing the cement content keeping the strength of concrete unaffected. Concrete mix design was performed for different grades of concrete and water cement ratio. This study presents the technique of optimisation of concrete mix design applying Genetic Algorithms using a developed MATLAB program. Minimising the proportions or quantities of materials without affecting its functional characteristics in a concrete mix results in most cost efficient design process. Economical design can be better achieved by optimising the quantities of materials without affecting functionalities of structures. Most of the engineering construction projects of bridges, dams consume huge quantities of concrete and other materials.
