Compression and workability behavior of chopped glass fiber reinforced concrete

Abstract

Most concrete structures showed some traces of cracks to some extent due to shrinkage and tension. Cracks decrease the durability of the concrete structure. To overcome this challenge this initiative has been taken and the research attempted to investigate chopped E-glass fiber reinforced concrete (GFRC) on the C-25 strength concrete production. Glass fibers were added with varying percentages from 0.05%, 0.1%, 0.15%, and 0.2% by the total weight of the cement. Workability and compressive strength tests were performed in the laboratory.The specimen made experimentally with glass fiber reinforced concrete was compared to the strength expected from the control concrete. The concrete's workability, both controlled and GFRC, was assessed using the slump test and correlated with its strength and quality. After 28 days of curing observed that 0.10% fiberglass content strength is increased and workability is decreased as the fiberglass content increases. Besides, concretes with fibers glass containing more than 0.15% have shown fewer results than concrete with no fibers.
