The development of advancements in concrete technology might lessen the amount of natural resources destroyed, thereby reducing the pollutants released into the environment. Currently, industries produce large amounts of fly ash, which adversely affects the environment and human health. Recent studies have shown that additional cementitious materials can improve various concrete qualities. These materials include fly ash, slag, silica fume, metakaolin, rice husk, and hypo sludge. These materials not only enhance the properties of fresh and hardened concrete but also help constructors save money. The aim of this study is to determine whether thermal industrial waste can partially replace cement in concrete manufacturing. Specifically, fly ash was tested as an additional cementitious ingredient to replace conventional concrete. It was added to the cement in different amounts: 0% (fly ash-free), 5%, 10%, and 20% by weight of cement to produce the M-20 mix. Concrete mixtures were created, tested, and their compressive strengths were compared to those of conventional concrete. Results were collected up to 28 days after curing to assess the strength attributes. The use of 5% fly ash results in a decrease in strength, but it is not significant. For 5% replacement of cement, the strength was found to be 2984.57 psi, which is satisfactory.
