An experimental investigation on properties of concrete by using silica fume and glass fibre as admixture

Abstract

Abstract High Performance Concrete (HPC) has been used in various structures all over the world since last two decades. Recently a few infrastructure projects have also seen specific application of high-performance concrete. The development of High Performance Concrete (HPC) has brought about the essential need for additives both chemical and mineral to improve the performance of concrete. Most of the developments across the work have been supported by continuous improvement of these admixtures. To attain the set out objectives of the present investigation, cement has been replaced partially with silica fume 20%. Glass fibres 1% to produce High Performance Concrete. Hence, an attempt has been made in the present investigation to study the behaviour of Natural sand and M-sand. Natural Sand has been replaced with M-sand in three different percentages viz. 0, 50, 100%. HPC is tested for compression strength.
