Summary: This study investigated the hydration characteristics of cement composites incorporating plant cellulose microfibers (CMFs) as a sustainable additive. The findings suggest that a higher amount of CMFs generally leads to a larger delay in the setting time and lower compressive strength, but mixtures with 0.3-0.6% CMFs showed reasonably high strengths compared to plain mixtures. The CMFs refined the pore structures of the cement composites and promoted further hydration.

Summary: This study investigates the effects of fibre concentration on the mechanical response of welded glass-fibre-reinforced polypropylene (GF-PP). Experimental observations reveal a significant reduction in weld ratio, up to 60%, indicating a decreased strength compared to the bulk material. Increasing fibre content in the welded material results in a decrease in stress at break and strain at the maximum stress. The use of DIC technique and X-ray microtomography further confirms the localized strain amplification in the welded zone due to the significant increase in fibre density.

This study designed a directional eddy-current (EC) probe to evaluate the detectability of out-of-plane wrinkles. Experimental evaluations and finite element modeling were conducted to better understand the relationship between eddy-current density and defect detection. The findings suggest that the probe configuration with an asymmetric driver coil and differential pickup coils shows the best capability for wrinkle detection.
