        abstract = {Now-a-days, there is a great need to reduce the cost of the building materials and hence,the cost of construction so that the “dream of a shelter”to every citizen of our country could be achieved at an affordable cost.The cost for the construction of buildings could be reduced considerably by utilizing industrial by-products wherever possible in the buildings. . This project presents the results of an experimental investigation carried out to find the suitability of addition of silica fume in M20 grade  concrete. Two grades of  Portland pozzolana Cement (PPC) were used in the M20  grade concrete, namely PPC. Silica fume, which is non-metallic and non-hazardous waste material obtained during the production of elemental silicon or alloys containing silicon in electric arc furnace, is used in this project. The main parameter investigated in this study is the addition of silica fume in varying dosages of 0%, 2.5%, 5%, 7.5%, 10%, 12.5% in M20 grade concrete with a water-cement ratio of 0.5. Concrete cube specimens were cast for M20  grade concrete using various dosages of silica fume as indicated above and tested at the age of 7, 14 and 28 days. The investigation revealed that the addition of silica fume develop the compressive strength, sufficient for construction purposes. The results for concrete indicated that Workability decreased significantly as silica fume percentage increases compared with the normal concrete without addition of silica fume.},
