Abstract: Concrete is the most used building material in the world and its use eclipses all other building materials. Sand is an ingredient of any concrete and the addition of treated sawdust reduces the amount of sand that is required. Even though sawdust is added, it does not eliminate the need for sand or the other ingredients found in concrete. However, in order to reduce the environmental impact of mining ingredients, this application has replaced some of the sand that is used in concrete with sawdust that has been saturated. The finished product retains the composition and durability of the finished concrete product and particularly the strength and durability of concrete.
