Smaller sand particle with smaller Stokes number responds to the fluid flow faster. • Erosion pattern and eroded depth are strongly influenced by the particle size. • Different particle size can cause different erosion mechanism and erosion rate. • Both eroded profiles, "U" and "W", are found when particle size ranging from 50 to ...

The challenging issue of demand for sand in concrete can be addressed by exploring alternative materials. Mechanism sand [12], aeolian sand [13], waste foundry sand [14], construction demolition waste [15], industrial by-products (such as coal ash, aged clay tailings, copper tailings) [16], [17], [18], and sea sand [19] are among the …
