Sawdust is a by-product of cutting, grinding, drilling, sanding, or otherwise pulverizing wood with a saw or other tool. It is composed of fine particles of wood. Certain animals, birds and insects which live in wood, such as the carpenter ant are also responsible for producing the saw dust. Sawdust has a variety of other practical uses, including serving as mulch, as an alternative to clay cat litter, or as a fuel. Mixed with water and frozen, it forms pyrite, a slow-melting, much stronger form of ice. Sawdust can be used as alternative substitute for fine aggregate in concrete production. In this project contains of partial replacement of sawdust & m-sand used with rivers sand for manufacturing a concrete. It gives optimum results about strength and different tests to be conducted on this project to find the different behavior of concrete by using a sawdust and m-sand. This project contains tests of impact load strength and by using sawdust so the special test consists of acoustic tests. Now way days in tunnel is lining with concrete so possibility of sudden impact load to be applied so we know the impact strength of the concrete. Wood as an acoustic material so its waste used in concrete so has to absorb some quantity of sound so as this factor the acoustic test to be condtion discussed under this project.
