Effect of polypropylene fiber length on the mechanical properties, frost resistance, and microstructure of silica fume-modified self-compacting concrete

This study investigates the influence of polypropylene fiber length (6–20 mm) on the mechanical properties, frost resistance, density, and microstructure of silica fume-modified self-compacting concrete (SCC). Microstructural analysis by scanning electron microscopy (SEM) was performed on the fiber-free reference mixtu...
