MECHANICAL PROPERTIES OF LATEX MODIFIED NYLON FIBREREINFORCED CONCRETE WITH PARTIAL REPLACEMENT OFCEMENT BY FLYASHJayaprakash Sridhar, Dhanapal Jegatheeswaran and Bimalendu Dash
Nylon fibers are used as strengthening material to increase the mechanical properties of concrete.In thisstudy mechanical properties of concrete containing latex modified nylon fiber reinforced concrete wasassessed with fractional substitution of cement by flyash for M40 grade concrete at 7 days, 14 days and 28days of curing. The dosage of fibres used in this study was 0.05%, 0.1% and 0.15% of volume fraction.Cement was replaced with fly ash at a percentage of 10%, 15%, 20% by weight. SBR latex was varied at arate of 0.05%, 0.1%, 0.15% to the total cementitious content in concrete. Cube, cylinder and prism specimensare tested to determine the compressive, split tensile and flexural strength at 7 days and 28 days curing.Results shows that Nylon fiber reinforced concrete with 0.15% of fiber, 0.05% SBR Latex with 10% hashigher influence on flexural strength, split tensile strength and compressive strength of concrete.
