•Spalling damage is the main damage mode of RC slabs under close-in blast.•Higher charge weight leads to more fragments and propels them to a farther distance.•The proportion of small fragments increases as the charge weight increases.•Fragments velocity can be up to 100 m/s under 6kg TNT at 0.4m st...
