AN EXPERIMENTAL ANALYSIS OF SILICA FUME AND BLAST FURNACE SLAG WITH PARTIAL REPLACEMENT OF CEMENT AND SAND
Keywords:
Concrete cubes, tensile strength, blast furnace slag, construction materialAbstract
Growth in urbanization require large amount of construction material such as sand, cement, aggregates and due to high demand of these material their cost day by day increases. So it is very beneficial to replace these materials with some other material whose properties resemble with them. In this research we use silica fume and blast furnace slag with partial replacement of cement and sand. Concrete cubes and beams are prepared and their compressive strength, flexural strength and workability are tested and compared with the concrete have nominal mix. The concrete prepared is M25. The blast furnace slag used in the percentage of 0 percent, 10 percent, 20 percent, 30 percent & and silica fume in the percentage of 0 percent, 8 percent &16 percent separately. it is concluded that compressive strength and tensile strength is increases with increase in the percentage of blast furnace slag and silica fume and after that decreases.
