Applicability of fractal models for characterising pore structure of hybrid basalt–polypropylene fibre-reinforced concrete

Abstract The pore-structure characteristics of hybrid basalt–polypropylene fibre-reinforced concrete were investigated by using mercury intrusion porosimetry. applicability various fractal models in characterising the HBPRC pore structure was compared. results show that types and content fibres different influences on cumulative volume basalt-polypropylene concrete. Compared with pore-volume solid mass, surface area is more significant. Furthermore, pore-surface model established based energy conservation relationship during accurate effective for characterization dimension research can provide important theoretical guidance study
