MECHANICAL AND DURABILITY STUDY ON STEEL AND GLASS FIBERS BASED CEMENTITIOUS COMPOSITE

Abstract

The study targets the utilization of steel and glass fibers in developing engineered cementitious composite. Compressive strength (CS) tests, split tensile strength (ST) tests, and static flexure tests were conducted to comment on the mechanical behavior of the composites. The durability properties of the designed mixes are commented on using rapid chloride penetration (RCPT) and sulfate tests. The CS of the conventional mix C-40 is compared with the S-ECC and G-ECC. The tested G-ECC specimens were more ductile than the S-ECC specimens and their respective variants. The S-ECC produced better results for both the CS and ST tests than the S-ECC and its variants. The conventional mixes of C-40 resulted in high penetration values than the composites prepared with steel and glass fiber inclusion. The destruction of the aluminosilicate skeleton, which leads to the liberation of silicic acid and sodium ions, is responsible for the deterioration caused during sulfate attack tests.
