Response of SIFCON two-way slabs under impact loading

An experimental program was carried out to investigate the behaviour of slurry-infiltrated fibrous concrete (SIFCON) slabs under impact loading. Fibre-reinforced concrete (FRC), reinforced cement concrete (RCC) and plain cement concrete (PCC) slabs were also cast and tested for comparison purposes. The impact force was delivered with a steel ball drop weight. The test results revealed that SIFCON slabs with 12% fibre volume fraction exhibit excellent performance in strength and energy-absorption characteristics when compared with other slab specimens. Regression models have been developed to estimate the energy absorption for SIFCON slab specimens.
