EXPERIMENTAL STUDY ON HARDENED CONCRETE BY USING STEEL FIBERS WITH MINERAL ADMIXTURE

Concrete is probably the most extensively used construction material in the world. The main ingredient in the conventional concrete is Portland cement. The amount of cement production emits approximately equal amount of carbon dioxide into the atmosphere. Cement production is consuming significant amount of natural resources. That has brought pressures to reduce cement consumption by the use of supplementary materials. Availability of mineral admixtures marked opening of a new era for designing concrete mix of higher and higher strength. Fly Ash and silica fume is a new mineral admixture, whose potential is not fully utilized. Moreover only limited studies have been carried out in India on the use of silica fume for the development of high strength concrete with addition of steel fibers.
