Abstract
The properties of the products of gravel crushing recycled concrete as inert aggregate concrete mixtures
Study the properties of rubble, produced by crushing recycled concrete. Secondary crushing of concrete products in the mass contains 20% of the grains gravel fraction 20-40 mm and 40-50% of the fraction 5-20 mm. The resulting rubble is the brand for divisibility 300-600, and its abrasion is within the A2-A4. Both indices increase with increasing grain size. To assess the grain shape of rubble offered index φs, which is the ratio of grain surface rubble to the surface of the cube of equal volume.
