| Popis: | This research examines the mechanical characteristics of self-compacting lightweight concrete (SCLC) produced with limestone powder and reinforced by polypropylene fiber. The compressive strength, impact resistance, elastic modulus, splitting tensile strength, and flexural strength are measured at the ages of 28 days, and the toughness index of the specimens is determined from load-deflection relationships. The test results reveal that adding fiber does not affect the compressive strength, but it slightly improves the elastic modulus and the splitting tensile strength. The impact resistance and flexural properties show the most remarkable improvement; this enhancement is more superior when macro and hybrid fiber are added instead of a single microfiber with a greater improvement when the highest macro fiber content is used in the hybrid concrete specimens. |
