Currently, there is a significant demand for residential and commercial structures due to the population's fast increase. Concrete is essential for the construction of every building. To prepare concrete, several components are required. Owing to the ongoing development activity, these natural resources running out in an effort to preserve these assets, found marble dust here when researching for a substitute, why due to the fact that it is a byproduct of the marble industry .It has an impact on both the environment and people's health, therefore to reduce these damages and preserve our natural resources, intended to use this marble dust in place of fine aggregate .We intended to use banana fibre in order to improve the strength to the pavement. The percentages of substitution for marble dust are 0%, 5%, 10%, 15%, 20%, and 25%. Additionally, a proportion of 0%, 1.1%, 2.1%, 3.1%, 4.1%, and 5.1% of banana fibre is added. By using these percentages, we cast various cubes, and after evaluating them, we came to the conclusion that a 15% replacement provided the greatest results overall. And the tests we ran were the Compressive strength and Split Tensile Test. We utilised M20 concrete, which is a grade.

The world is rapidly changing, and building construction is becoming increasingly important. If we look at it closely, the use of concrete increases, resulting in a scarcity of natural resources. To save our natural resources, replace some of the concrete proportions with the following methods. Using equal quantities of fly ash and metakaolin, fly ash and GGBS as admixtures in geopolymer concrete (50-50%). The results of the compressive strength split tensile strength, for 28, 56 and day strength tests. The combination of two admixtures and a super plasticizer allowed the strength parameters to be increased.
