predict the recycled aggregate concrete (RAC) compressive strength and Interfacial Transition Zone (ITZ). Writing computer programs is utilized to tackle many plan issues that are hard to settle by regular strategies for designing mechanics. Software has been read the data from previous research and analyse the outcomes at different Percentages of micro silica and recycled coarse aggregate. We are going to present an approach to modeling Of Recycled Aggregate Concrete Using Programming Languages. Results show that the predictive performance compressive strength of recycled aggregate concrete with micro silica. This thesis targets to a predictive approach to cost-saving RAC mixture designs.
