文摘

Micro X-ray computed tomography (μXCT) images obtained for UHPFRC with 24.8 μm resolution. A two-scale homogenisation method developed for UHPFRC based on CT images and pore sizes. The homogenised elastic moduli compared satisfactorily with experimental data. The method’s capability of optimising fibre orientation and volume fraction demonstrated.
