Abstract The air-void structure of hybrid basalt-polypropylene fibre reinforced concrete (HBPRC) was investigated by using a Rapid Air 457 air-void analyser. The effects of basalt fibre, polypropylene fibre and hybrid basalt-polypropylene fibre on the cumulative air-void content and air-void surface fractal dimensions (D_S) of concrete were analysed. The results indicate that the air-voids structure of the HBPRC has distinct fractal characteristics and its fractal features are scale-dependent and the incorporation of basalt fibre, polypropylene fibre and hybrid basalt-polypropylene fibre increases the cumulative air-void content of the concrete by 76.5% to 354.1%, and that the cumulative air-void content of the concrete increases with the increase of fibre content. The D_S of HBPRC in the small-pore, medium-pore, macroporous and superporous regions increase sequentially, although there are no physical characteristics in the region with pore diameters greater than 1 500 μm. The incorporation of fibre has a significant effect on the D_S of the macroporous and superporous regions. The D_S of the macroporous and superporous zones are increased with 0.1% (volume fraction, the same below) basalt and 0.1% polypropylene fibre alone; the addition of 0.1% hybrid basalt-polypropylene fibre has little effect on the D_S of the macroporous and superporous region; the addition of 0.2% hybrid basalt-polypropylene fibre significantly reduces the D_S of the superporous region. Through microscopic analysis, it is suggested that the suppressive effect of the fibre-formed network structure on bubble merging is the main reason for the increase of D_S of the macroporous and superporous zones, while the weak dispersion of the fibres and prolonged agitation lead to the deterioration of the pore structure in the macroporous and superporous zones.
