Abstract

Steel Fiber Reinforced Concrete (SFRC) enhances concrete's mechanical properties, such as tensile and compressive strength, as well as abrasion resistance. At PT. Waskita Beton Precast Plant Karawang, waste from prestressed strands (PC strand) has raised environmental concerns. This study examines the effect of adding PC strand waste to concrete's mechanical properties. Tests were performed on concrete beams (60x15x15 cm) for flexural strength, cylinders (30x15 cm) for compressive strength, and smaller cylinders (10x6.67 cm) for abrasion resistance, with variations of PC strand content at 7, 14, and 28 days.
The results show that adding 1.5% PC strand significantly improved the concrete's properties. Compressive strength increased by 13.15% (4.13 MPa), and flexural strength rose by 57.84% (2.62 MPa) with 2.0% PC strand. The abrasion test indicated the lowest mass loss in concrete without PC strand. The optimal mix, with 1.5% PC strand, achieved a compressive strength of 34.64 MPa, flexural strength of 6.58 MPa, and mass loss of 1.77 grams. This concrete is suitable for rigid pavement and bridge structures.
