Abstract
Sand is used primarily for construction in India. Sand will become scarce as a result of its rapid use. Robodust and Sawdust is utilized in place of the sand to combat this scarce of shortage. Western nations and a few Indian states have recognized the use of crusher dust, also known as Robosand, as a building material. Crushed stone dust has been extensively studied as a river sand substitute, and it has been found that it can be used to partially substitute for natural sand in concrete. Compressive and split tensile strengths of sawdust and robosand in the proportion utilized as fine aggregates in concrete were going to be examined. This project's primary goal is to examine the behavior of M25 grade concrete with a 1:1:2 mix design and a water-to-cement ratio of 0.45. In this instance, 25%, 30% of robosand, and 5% sawdust were used to replace some of the fine aggregate. One of the substitutes for river sand is the crusher dust generated by granite crushers and by-products from a quarry.
