In present scenario of pandemic, IT organisations and Pharmaceutical organisations are growing with full momentum, but other organisations also slowly coming back to track. Banking organisations are first organisations among the recovering sectors. Then comes the industrial and capital goods sectors which are looking interesting and could be among best performers this year. Hence, after the top performing IT and Pharmaceutical organisations, Banking, Industrial and Capital Goods organisations will be top performers this year. Then next top performing organisation would be construction materials organisation like cement and steel sectors.
Fibre reinforced concrete is a composite material essentially consisting of conventional concrete or mortar reinforced by random dispersal of short, discontinuous and discrete fine fibres of 25-50mm long and 0.25 to 0.50 mm in diameter, consisting of 4 to 5% weight and of specific geometry. The fibres interlock and entangle around aggregate particles and considerably reduce the normal workability while mix becomes more cohesive and less prone to segregation. The fibres suitable for reinforcing the concrete have been produced froom steel, glass and organic polymers. Naturally occuring asbestos and vegetable fibres, such as jute are also used for reinforcement. Steel, carbon and glass have higher elastic moduli than cement mortar matrix and polypropylene and vegetable fibres are low modulus fibres. High modulus fibres improve both flexural and impact resistance simultaneously whereas low modulus fibre improve impact resistance of concrete but do not contribute much to flexural strength. ...
