Strength Modeling of High Strength Concrete

IOSR Journal of Mechanical and Civil Engineering, 2014
Silica fume is being used all over the world for many years in the area where high strength and durable concrete were required, and it also improves the characteristicsof both fresh and hard concrete. Incorporation of the silica fume increases the mechanical properties of high strength concrete than the conventional concrete.
