Influence of Addition of Glass Fibre on Concrete

Abstract

Abstract Fibres used to develop high performance concrete. Fibres such as glass, carbon, polypropylene and aramid fibres need to be improved in view of global sustainable development. Long term durability is achieved with the development of a high alkaline resistance fibre dispersion. This system was called reinforced concrete with glass fibre alkali resistance. To decide compressive and split rigidity, modulus of elasticity, modulus of crack and quick chloride penetrability tests for concrete grade M20 and M30 with and without fluctuating level of glass strands. The specimens were cast and tested at 28 days. The percentage of addition of glass fibres marginally increased the strength of compressive, flexural, split tensile for M20 and M30 grades of concrete when specimens tested at 28 days. A reduction in bleeding and permeability is also observed.
