ABSTRACT The world is looking at the use of advanced materials and almost all the fields of engineering Nowadays. The same trend is observed in field or construction engineering in order the performance of construction materials One of the areas is to use silica fume (S.F) as a cementations material the cement to produce high performance concrete. SF is a byproduct from ferro -silicon industry, It is believed that the use of silica fume in concrete a partial replacement not only increases the strength of concrete but its durability also. The use of SF also facilitates the disposal of industrial otherwise it needs a lot of the area to be dumped and also causing the environmental hazardous effects. This experimental study is undertaken to investigate the effect of silica fume on the strength properties of concrete when it is used as a partial replacement. The silica fume was used from 0-20% by total weight of cement with an increment of 2.5%. The concrete was produced with the ratio of I with w/c ratio of 0.48 and 0.50. The specimens of standard size were cast and tested at 28-days age. The Effectiveness of S.F was investigated in terms of compressive and tensile strength of concrete. The results were compared to those of concrete without S.F. The results revealed that the Compressive and tensile strength of concrete adequately enhances with the use of SF. https://tinyurl.com/4w4wm9kz https://tinyurl.com/4w4wm9kz
