· One was sieved with the 4750 µm square hole sieve, namely coarse river sand (CRS) and the other was obtained with the 2360 µm square hole sieve, namely fine river sand (FRS). Especially, the gradation and size of CRS remain the same as that of fine aggregate in traditional concrete. For comparison, ultrafine silica sand of 104–212 µm was also selected. The particle size distributions of ...
