Demonstration on the coalescence of fiber reinforced concrete with self-compacting concrete

Abstract

Abstract Self compacting concrete and fibre reinforced concrete are segregated as high performance concrete (HPC) due to its proportions and properties. HPC may be a specialised concrete designed to produce many edges within the construction structures that can't invariably be achieved habitually mistreatment typical ingredients, traditional commixture and solidifying practices. Besides, its ingredients and proportions are specifically chosen and developed for particularly appropriate properties for the expected use of the structure. Inclusion of fibres into self compacting concrete will produce fibre reinforced self compacting concrete with superior properties in the fresh and hardened state concrete. The strengthened fibres in concrete might improve the compressive strength, tensile strength, flexural strength, impact strength, toughness and drying shrinkage. Modification to the fiber reinforced self compacting concrete mixtures have been done by using different types of fibers. This study was conducted to investigate the properties of fiber reinforced self-compacting concrete with hybrid fibres, steel fibres and nylon fibres reinforced self compacting concrete. The compressive strength results show that the use of 0.3% of micro Steel fibres and 0.1% of nylon fibres increases the compressive strength by about 31.5% on comparing it with conventional concrete. The split tensile strength results show that the use of 0.3% of micro steel fibres and 0.1% of nylon fibres increases the compressive strength by about 17.95% on comparing it with conventional concrete. The flexural strength results show that the use of 0.3% of micro steel fibres and 0.1% of nylon fibres show similar results to that of conventional concrete.
