Abstract: | In any developing economy like India, there is always a constant need to newlineupgrade infrastructural requirements. But due to the impact of environmental newlinequality coupled with the ever increasing material scarcity, there is a need to newlinedevelop new materials and devise new approaches to counter these issues. newlineProper planning and environmental friendly designs are the need of the hour at newlinethe designing and planning stages of the construction. This study concentrates newlineon the behaviour of concrete blended with waste and eco-friendly materials newlinelike fly ash, steel, polypropylene and nylon fibres. Eexperiments were done newlinewith two different mix proportions for M25 grade concrete. The first mix was newlinedesigned without fly ash and experiments were conducted to study the newlinephysical, mechanical properties of concrete and flexural behaviour of RC newlinebeams with nylon, polypropylene and steel fibres. The fibres used in this study newlinewere nylon monofilament, polypropylene monofilament and steel hooked end newlinefibres. All specimens were tested at 7 days of curing in this phase. These newlinefibres were taken by weight of cement in proportion of 0.5%, 1% and 1.5%. In newlinethe second mix, 40% cement was replaced with fly ash. Nylon, polypropylene newlineand steel fibres were taken by volume of concrete in proportion of 0.5%, 1%, newline1.5% and 2%. Experimental investigations were carried out to study the newlinemechanical properties, durability and microstructural behaviour of concrete newlinewith fibres. Flexural behaviour of RC beams with these fibres were also newlinestudied with respect to crack pattern, crack width, load-deflection, momentrotation, newlinestiffness, flexibility and ductility. The specimens with fly ash were newlinetested at 56 days of curing and all other specimens were tested at 7, 14 and 28 newlinedays of curing. The fibres used in the second mix were nylon (untangle), newlinepolypropylene (fibrillated) and steel (hooked end). Workability of fresh newlineconcrete was measured using slump cone. In order to increase the workability, newline1.3% superplasticizer by weight of cement is added in the first phase. |
