This is because a high fines content in natural sand usually indicates increased silt, clay orshaleconcentration, which is detrimental to both fresh and hardened concrete properties. In crushed sand, thepresence of these contaminants is rare (at least in Scandinavia) and some level of fines would normally increase the content of filler-modified cement paste, thus helping with lubrication between the coarser aggregates particles (≥ 0.125…
