Concrete was created as a stronger and more resistant building material as it was worked upon over time. Gradually, the man figured out how to create it, transport it, and utilize it more efficiently. We know that concrete is made from cement, sand, aggregate, and water. Out of these, some of them may be replaced with some other material like wheat straw ash, rice husk ash, fly ash, etc. for various purposes, mostly to utilize waste material without affecting the important properties of concrete beyond acceptable limits. This study deals with an investigation into the properties of concrete by partial replacement of sand with wheat straw ash and the addition of polypropylene fiber in it. Wheat Straw is the por- tion of leftovers of the wheat crop after it is harvested. In most countries, it is a waste. People burn it and cause pollution and health hazards, good strength and high per- formance in concrete are very much required in future construction work. It is felt that fiber dispersion in concrete is one method to improve the structural characteristics of concrete. Keywords Polypropylene Fiber, wheat Straw Ash, rice husk ash, concrete 1. Introduction Concrete is the more widely utilized construction material on the planet earth, particularly in evolving and developing na- tions. It is the world's most abundantly used building material and has a history that goes back to the Romans and ancient Egyptians. Considering that concrete is used twice the rate as all other building materials in construction, a focus on quality, Open Access
