Assessment of Cementitious Composites by In-Situ SEM Bending Test

The SEM photographs presented on Figs 5 and 6 show the difference observed in the failure modes of the specimens subjected to the accelerated ageing process.

Figure 5 - Typical failure mode of the bundle of fibres subjected to accelerated ageing process.

Figure 6 - Typical failure mode of the bundle of fibres subjected to normal ageing process.
