Abstract:
An experimental study was carried out on fiber-reinforced glass aggregate concrete slabs under a central patch load. The slab specimens were reinforced either with randomly distributed short fibers or with continuous fiber mesh with equal fiber volume ratios. The influences of fiber type, form and volume ratio on the two-way bending behavior, and punching shear capacity of the glass concrete slab were investigated. Test results revealed that fiber mesh is decidedly more effective in bending than randomly distributed fibers; however, randomly distributed fibers are somewhat more effective in punching shear. The shape and location of the critical punching shear perimeter is independent of fiber type, form, and volume ratio. But crushed glass aggregate has some influence on both strength and failure mode of the slabs.
