No construction work is possible without bricks because of bricks are used in buildings as well as in pavement. Since many centuries brick-making has been practiced by human beings, presently bricks are easily made by the use of the machine but in old day’s bricks are manufactured by own hand using wooden or steel moulds. For any types of buildings, amajor part of the construction cost is just belongs to bricks work. Bricks walls are not a load bearing elements but they column. Due to high dead weight, the size of the load-bearing element needs to be increased which increase the cost of project disasterly that’s why in modern engineeringlightweight and low-cost building material is needed. In this research work, hypo-sludge (waste of paper industry) and rice husk ash (waste from agriculture industry) were use. Both the materials are waste product one from paper industries and other from agriculture industry and both cause environmental pollution and disposal problem. Use of such product help to reduce the environmental pollution and they are low-cost materials which also helps to keep project cost low. In this research work, hypo-sludge is used as cementing material and rice husk ash is used as fine aggregate. In this research work, different variations of hypo-sludge and rice husk ash (RHA) is used for manufacturing bricks sample after that bricks physical properties is compare by ordinary clay bricks, fly ash bricks, and with their different composition. For this research work Dimension Analysis, Initial Rate of Absorption, Compressive Strength Test, Water Absorption Test, Soundness Test, and Efflorescence Test is conducted for the analysis of the physical properties of the bricks. from the analysis by etabs conclusion can be made that bending moments and shear forces are less in structure made up of hypo sludge bricks as compare to conventional structures (structure those are made up of either clay bricks or fly ash bricks) on every storey of building structure. The weight of a RHA-HS Brick is approximately 2.5 to 2.7 kg while clay brick weights approximately 3.0 kg, it causes approximately 13.33% reduction in dead load of structure due to partition walls which on the other hand causes reduction in percentage of steel used in all related load carrying structure section like Beams, Columns, and Footing.
