Experimental study on Behaviour of Concrete by using Silica Fume and Saw Dust in Concrete

Abstract: The most widely used construction material on the planet is concrete. Day by day varied transformation is taking place in the type and quality of concrete being used. High performance concrete is one of the modern concretes which is able to achieve such type of properties at better extent. Concrete is the backbone of every country for its development work. The quality and type of concrete being used have undergone diverse revolution The major transformation in the concrete technology includes the enhanced strength of concrete, which increased performance of concrete and introduction of various mineral admixtures Various tests were conducted to evaluate the effect of Silica fume and Saw Dust on compressive, splitting tensile and flexural strength test. Silica fume was used as a partial replacement of cement at the percentage of 2.5%, 5%, 7.5%, 10% 12.5%, 15%, 17.5% and Saw Dust was used as replacement of sand for the percentages mentioned above. Slump flow was carried out for rheological properties and compressive strength, split tensile and flexure tests were carried out to know the mechanical properties.
