Experimental Study on Fibre Reinforced High Volume Fly Ash Concrete for RCC Construction
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 4
Abstract
Road projects in future have to be environmental friendly and cost effective apart from being safe so that society at large is benefited by the huge investments made in the infrastructure projects. To achieve this, component materials of the pavement system have to be optimized with reference to behavior, performance, cost effectiveness, and sustainability to be considered. Experimental programmers had to be conducted to obtain the fatigue-lives of concrete at various stress levels. Recent environmental policies and regulations concerning the disposal of by products have increased the need to use of fly ash in concrete. In the present scenario, High-volume fly ash (HVFA) concrete has emerged as construction material. This present investigation focused on the performance of economical and viable concrete pavements made with hybrid fiber and high volume fly ash. The experimental investigation was carried out to evaluate the strength properties of concrete in which cement was partially replaced with Class F fly ash. High Volume Fly ash was replaced with different percentages of 55%, 60% and 65%of Class F fly ash by weight of cement. Hybridization of two different types fibers were used at different volume fractions. Tests were performed on the compressive strength and flexural strength at 7 and 28 days. Test results indicated there is a appreciable improvement in the strength properties of hybrid fiber reinforced HVFA concrete. It was also suggested that a large quantity of fly ash with discrete fiber reinforcement will enhance the strength characteristics and can be effectively used for the long term performance of concrete pavements.
