Abstract
Concrete is most widely used construction material in the world. Now a days the world is witnessing the construction of more and more challenging and difficult engineering structures. So, the concrete need to possess very high strength and sufficient workability. Researchers all over the world are developing high performance concrete by adding various fibers, admixtures in different proportions. Various fibers like glass, carbon, poly propylene and aramid fibers provide improvement in concrete properties like tensile strength, fatigue characteristic, durability, shrinkage, impact, erosion resistance and serviceability of concrete. Because of such characteristics fiber reinforced concrete has found many applications in civil engineering field GFRC is a recent introduction in the field of concrete technology. GFRC has advantage of being light weight, high compressive strength and flexural strength. To improve the long term durability and Alkali resistance glass fiber reinforced concrete is also invented. Carbon fiber is one kind of nonmetal fibrous material with high strength, high modulus, resistance to high temperature, resistance to acid and alkali corrosion and good conductivity, it possess fine performance of carbon as well as flexibility of fiber. The aim of the work is to study the properties of the effect of glass fibers as well as carbon fibers as reinforcement in the concrete for different proportions from the research work which is already carried out by the researchers.This project deals with investigation for M20 grade of concrete to study the compressive strength , split tensile strength and flexure strength of concrete containing glass fibers of 1.5% and carbon fibers of 1.5% and the combination of glass and carbon fibers at a % of (0.5%+1%) adding to the weight of cement. Tests will be done clearly shows percentage increase in 7, 14 & 28 days.
