Studi Eksperimental Perbandingan Kapasitas Slab On Ground Bertulangan Wiremesh Baja D8 Dan GFRP Mesh D8

Slab on Ground (SoG) is a concrete slab widely used in warehouses, parking areas,and industrial buildings. Reinforcement is required to improve its load-carrying
capacity, control deflection, and limit crack development. This study aimed to compare the performance of Slab on Ground reinforced with D8 Steel Wire Mesh and D8 GFRP Mesh under concentrated loading in terms of maximum load capacity, deflection, and crack pattern. An experimental method was employed using four concrete slab specimens measuring 400 × 400 × 100 mm with a design compressive strength of 25 MPa, consisting of two specimens reinforced with D8 Steel Wire Mesh and tw specimens reinforced with D8 GFRP Mesh. Prior to testing, the Base B layer was compacted and evaluated using the Sand Cone method, resulting in a field compaction degree of 74%. The specimens were tested at the age of 28 days using a hydraulic. piston, while the maximum load, deflection, and crack patterns were observed. The results showed that the maximum load capacities of the steel wire mesh specimens were 154 kN and 167 kN, whereas those of the GFRP mesh specimens were 167 kN and 175 kN. The maximum deflection of the steel wire mesh specimens ranged from 16–17 mm, while the GFRP mesh specimens ranged from 18–24 mm.Crack propagation in both reinforcement types initiated at the loading point and extended toward the slab edges.These findings indicate that GFRP Mesh provides higher loadcarrying capacity than steel wire mesh but results in greater deflection, making it a promising alternative reinforcement for Slab on Ground.
