Concrete is considered a durable and strong material. Concrete is an admired material in construction and is consumed in high volume in India as well as globally. Fly ash being a by-product of coal burning is also produced in high quantities from the steel and thermal power sector of India. This research is based on utilizing the waste material in concrete as a restricted substitution of cement, finding a suitable mix that shows healthy mechanical properties for strength, durability, and workability, and validating test results with ANOVA statistical analysis. Low strength M20 and M25 concrete mixes were designed as per IS10262-2019 code guidelines and treated as a base mix. Cement was substituted with varying percentages of fly ash, ranging from 10% to 30%. These mixes were tested for compression and tension by casting 90 samples of cubes and cylinders of standard sizes and further testing. Test results suggest that restricted substitution of cement by Fly ash up to 20% shows a positive response. ANOVA test results were in line with the experimental data.
