<p>In recent years, researchers have utilized waste materials in concrete, which improved concrete performance, reduced harmful gas emissions from cement production, and addressed waste disposal problems. In this analysis, a step towards eco-friendly concrete has been made with the use of wood ash as a cement alternative in varying percentages, starting from 0% up to 15% by weight of binder in increments of 5%. Furthermore, to improve the tensile capacity of wood ash-based concrete, 1.0% nylon fiber is added to wooden ash-based concrete. Fresh properties of concrete were calculated through air content, slump, and fresh density tests. Strength properties were evaluated through compressive, tensile, flexural, and impact resistance tests. Finally, the study also considered the concrete cost strength relation with the substitution of wood ash and the addition of nylon fibers. Results indicate that the strength properties improved with wooden ash substitution up to 10%, and further substitution decreased the strength parameter of concrete. Wooden ash and nylon fiber synergically improved the concrete performance. However, a decrease in flowability was observed with the replacement of wooden ash. Maximum compressive and flexural strength was observed at 10% wooden ash which is 10.50% and 50% more than from the control mix respectively. Cost strength relation shows that a 10% substitution of wooden ash along with a 1.0% addition of nylon fiber decreased the overall cost of blend with strength properties as compared to the reference mix.</p>
