Strength of steel fibre reinforced concrete ground slabs

Abstract

Tests are reported on four full-scale concrete ground slabs. Two types of steel fibre have been used to reinforce the concrete, with fibre contents of 20 and 30 kg/m3, which is lower than the minimum recommended in the Chinese construction practice. It is found that flexural toughness has an effect on the load-carrying capacity of steel fibre reinforced concrete (SFRC) ground slabs. The ultimate load capacity of the ground slabs is assessed and compared with the test results from different sources. The load-carrying capacity of the SFRC ground floors with flexural toughness effect is assessed. The horizontal thrust induced by the friction between the slab and the subgrade is also analysed.
