Mar 01, 2014 Based on experimental evidences, it can be said that at full replacement of sand with recycled aggregates, the higher cement content in concrete masonry units is not promising. This may be attributed to the porous nature of crushed clay brick which significantly reduce the mechanical properties of concrete masonry units. 4.2.2.
Besides, is Stone dust good for drainage? Also called rock dust, stone dust is more prone than sand to settling and drainage problems when used as a base beneath walkway or patio pavers.Stone dust has a powdery texture because it results from stones being crushed. It also drains poorly, which is a problem in climates that receive a high amount of rainfall.
