This research paper focuses on bringing out advantages of using Python over current practices of computations for various parameters. A comparative study has been carried out for scrutinizing the results obtained during the analysis of different parameters of the concrete from Python along with those from manual as well as from other reputed research papers.Through this research we attempted to design a predictive software tool with the help of python programming libraries, which can predict the physical and micro structural properties of concrete like compressive strength and Interfacial Transition Zone(ITZ).The overall engineering properties of concrete in relation to the ITZ are beyond the scope of this research. However, ITZ and compressive strength of the concrete incorporated with Recycled aggregate and Microsilica at various percentages has been predicted precisely in this book.
