Enhancement the Strength of Conventional Concrete by using Fly Ash and Synthetic Fiber
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 5
Abstract
In this thesis the study on the enhancement the strength of conventional concrete by using fly ash and synthetic fiber and the results of an experimental study for enhancing compressive strength, split tensile strength and flexural strength of concrete using nylon fibers with the nominal mix, admixture (0.9%)), admixture (0.8%) and fly ash (10%)), (admixture and fly ash and fiber, used in cubes. Were casted with different volume fractions. The samples with added nylon fibers of 1% showed better results in compressive strength and split tensile strength, 1.5% for flexural strength. The cement replacement levels by fly ash are 10%, 15% and 20% for three water-cementitious materials (w/cm) ratio of 0.6, 0.45 and 0.35. Compressive strengths, compacting factors are evaluated at different age levels like at 3 hours, 7 and 28 days for the150 mm cube. The main objective of this thesis is mix the proportion of m10 grade concrete and enhancing its strength as per m30 grade concrete the fiber reinforced concrete is the relatively an effective construction of material in which the main use of the fibers is to bridge across the cracks that develop in concrete and the main aim was to carry out a comparative study on crack width on reinforced cement concrete (rcc) beams with and without the addition of fibers. By providing optimum dosage of volume fraction of asbestos fibers, studies on cracking behavior of asbestos fiber reinforced concrete (afrc) beams were made in concrete under flexure.
