This research aims to investigate Abstract - The depletion of natural resources and the possible advantages in mechanical characteristics, workability, and environmental sustainability by partly replacing standard components with fly ash and red soil.

environmental concerns have led to a growing interest in sustainable construction materials and practices. In this research, we look at the possibility of using red soil and fly ash in lieu of some of the cement and fine aggregate in concrete. Investigating these substitute materials' ability to improve concrete's mechanical and environmental performance is the main objective.

The results of this experimental investigation shed light on the practicality and efficiency of using red soil and fly ash in lieu of some of the cement and fine aggregate in concrete. The findings of this research could potentially contribute to the development of sustainable construction practices, reducing the environmental impact associated with conventional concrete production while maintaining or improving the performance of concrete structures.

The experimental program involves varying proportions of red soil and fly ash as substitutes for conventional fine aggregate and cement in concrete mix designs. The workability, compressive, flexural, and tensile strengths of the final concrete are the primary metrics being studied. The performance of the modified concrete mixes is evaluated using a battery of laboratory experiments, including slump, compressive, and tensile strength tests.

2. LITERATURE REVIEW Mr. Ashok Raajiv, (2015): used Red soil as the partially Replacement to the sand in M20 Grade concrete by adding the chemical properties of test like iron, aluminum, organic matter, magnesium, lime, potash, soda, phosphorus, Nitrogen for the red soil is replacement of fine aggregate. The following tests are performed: compressive strength (19.24 N/mm2 for 28 days), split tensile strength (1.81 N/mm2 for 28 days), water content, specific gravity (2.6) of red soil, and a partial replacement of sand with red soil. Using a blended M20 grade of 1:1.5:3 mix proportion of cement, fine aggregate, and coarse aggregate, the sand in concrete has been completed using red soil. The physical features of the tests are the basis for all of the excellent and correct outcomes that have been produced by the tests. Based on the results of the 28-day compressive strength test and split tensile tests, the red soil may be used as a substitute for fine aggregate.

Here we have used M25 grade concrete and also we have replaced the 20% of cement by fly ash and 10%, 20%, 30% & 40% of fine aggregate by the red soil. This research holds significance for sustainable construction practices, offering potential solutions for both waste management and the conservation of natural resources. Researchers and engineers working to improve concrete mix designs using locally accessible ingredients, encouraging eco-friendly building methods, and decreasing the industry's dependence on conventional raw materials may find some useful information in the results.

1. INTRODUCTION Environmental concerns and the pursuit of sustainable building techniques have recently shifted the focus to the use of alternative materials in concrete manufacturing. Substituting fly ash for some of the cement and red soil for some of the fine aggregate is one such method. The goal of this experimental investigation is to find out how adding these different components to concrete changes its performance and characteristics.

Dr. K. K Jain, Et al. ( 2001 ) : had substituted some of the cement with neutralized red dirt. Soil has a specific gravity of 3.15 with a particle size distribution of 12% clay, 80% silt, and 8% sand. The Ultratech grade is M43, and the concert grade is M45. The primary evaluation is the compressive strength test after 28 days. There was a drop in compressive strength at the 5% cement-neutralized red mud replacement level, but at the 10% and 15% levels, compressive strength rose. Various tests are conducted by the Replacement of cement by Neutralized Red mud by two types, a) Test on the cement and b) Test on hardened concrete. Test on cement- a) Standard consistency of

The pozzolanic characteristics of fly ash, a waste product of coal combustion in power plants, may improve the strength and longevity of concrete by aiding in the hydration process of cement. However, red soil is a great alternative to fine aggregate in concrete mixes due to its
