Concrete structural components exist in the buildings in different forms such as beams, columns etc., Utilization of industrial by-product in concrete offers technical, economic and environmental advantages which are greatest importance in the construction sector. In present situation the metal casting industries generate lot amount of foundry sand as by product. Foundry Sand (FS) is a by-product from the metal alloys casting industry with high silica content. Foundries recycle the sand many times, and when the sand is no longer recyclable, it is disposed of this is called Used Foundry Sand (UFS).The properties of UFS are similar to natural sand, which can use as replacement for natural sand. Another industrial waste is Bottom Ash (BA) is a by-product of the combustion of pulverized coal in the power plants. Although large amount of Fly Ash (FA) has already been utilized in construction industry as a partial replacement and mineral additive in cement production compare to that of BA. The BA are used as partial replacement for the cement, helps to make the concrete high dense and which reduce the permeability. Understanding the behaviour of structure during loading is important to develop an efficient structure. Hence reinforcing bars are introducing concrete in tension zone. This research paper deals with the Analytical and experimental studies on beams containing UFS and BA. The objective of this work is to investigate the flexural and shear behaviour of beams containing UFS and BA by analytical and experimental in M25 grade concrete. Here the fine aggregate is replaced with UFS by 30% and the cement is replaced with BA by 20% and 30%. Beams were modelled to be dominant in Flexure and Shear. Analysis was carried out in FEM based software ABAQUS. Hence analyse using software is an excellent alternative of destructive laboratory test.
