Concrete is good cements in binder. in compression. In we discuss about the different uses of addition of hemp fibers and combine replacement of Nano concrete is a form of concrete that contains cement with GGBS and sand with marble powder to the Portland cement particles with size not greater than 100 concrete. μm and also silica particles with size not greater than In this we use different percentages of GGBS and 500 μm, which fill voids that would otherwise occur in marble powder as replacement for cement and adding normal concrete, thereby substantially increasing the 0.5% of hemp fibers respectively. The percentages of material's strength. It is a product of high-energy GGBS and marble powder combinely replaced in M50 grade of concrete i.e, different percentages mixing (HEM) of cement, sand and water.
