The compressive strength of the concrete is improved when the cement, sand, and aggregate are combined in the right proportions and firmly linked together. Filler made from stone dust is a by-product of stone crushing operations and may be utilised in a variety of applications. In order to guarantee that the coarse aggregate is properly bonded together, stone dust is used in the building of the W.B.M. road. The production of fly ash, a waste product that is created in enormous amounts, is a by product of thermal power plants. The mixture that is produced by the combination of fly ash and cement has the same characteristics as cement itself. The bulk of the research was conducted by substituting fly ash for cement in the various experiments. Stone dust and fly ash are combined before being added to a concrete mix as part of a scientific experiment to study the behaviour of concrete. When constructing using stone dust and fly ash, the primary objective is to produce a structure that is both cost-effective and has a certain level of strength. In this particular experiment, stone dust is used to partially replace sand, while fly ash is used to partially replace cement in the mixture. Both of these materials are combined. It is anticipated that stone dust will fulfil the role of sand in the project to the extent of fifty percent, and that fly ash will perform the functions of zero, five, and ten percent of the cement. The concrete's workability is evaluated using a test called the "slump test," which involves pouring the concrete at an angle. After determining the compressive strength, flexural strength, split tensile strength, modulus of elasticity, and other parameters of the concrete, it is compared to conventional concrete of grade M40. This helps ensure that the concrete is strong enough for its intended use. The standards of the IS code are adhered to throughout each and every real test that is carried out.
