Comparison of Mechanical Properties Between Basalt and Alkali Resistant Glass Fiber in Cement Concrete
摘要
Over the past few years, composite materials have started replacing steel in construction as they provide more benefits in so many aspects of building construction. Out of all the categories of fabricating reinforcing fibers, the basalt fiber has become one of top priority in many uses. This research aims to compare the mechanical performance of concrete developed with use of basalt fibers (BF) and alkali resistant glass fiber (ARGF) after curing age of 7 and 28 days. The fibers used in study were added by weight of cement and performance of concrete upon the mechanical parameters provided an increase in compressive strength (CS) with BF as 26% at curing age of 28 days relative to concrete containing ARGF. While the flexural strength (FS) and split-tensile strength (STS) increased by 11.8% with use of ARGF relative to BF at curing age of 28 days. Concerning workability, beyond the dosage of 2% in case BF and ARGF, the concrete showed reduction in workability due to the occurrence of net like structures (Balling effect). Thereby, it surely indicates that each fiber has its own merits for use in particular type of loading, thus indicating a sure pathway for use hybrid fibers in concrete industry and making it sustainable.
