Mechanical Properties of Glass Fiber Reinforced Concrete(English)

Abstract

This paper described an experimental study of some mechanical properties of glass fibers reinforced mortar (GFRM) and concrete (GFRC), namely tensile, compressive strength and young`syoung`s modulus. The investigation is designed to find out the effect of glass fiber content (0, 600, 1000, and 1400) gm/m 3 on the mechanical properties of glass fiber reinforced concrete and mortar at 28 and 14 days respectively. The results indicate that the addition (600, 1000, 1400) gm/m 3 of glass fiber to concrete and mortar increased the splitting tensile strength by approximately (1,4.3,12.5)% and (5.4,7.7,17)% for concrete and mortar respectively. The results indicate also that compressive strength of concrete increased by ratios (3.6,7.1,9.3)% and for the mortar increases by (2) %for fibers content (600) gm/m 3 and (0.8,0.4)% for fibers content (1000,1400)gm/m 3 .Based on this study the young modulus of GFRC increased by (9.7,56.6,84) % due to glass fibers content in concrete. ‬
