Crushed sand is an aggregate of angular shape and surface roughness that hinders the self-compacting of the concrete mixtures. Combination with fine mineral admixtures will be a good solution to improve the rheological properties of the concrete, i.e. reducing the internal friction between the angular particles in the paste system, increasing ...
