Answer (1 of 7): Of course. Quite a standard procedure. We call it crusher dust, or manufactured sand. Dependent on the source rock and type of crusher, the particle shape is unlikely to be nice round grains, which makes for concrete that is not quite as nice to play with, but it is still far fr...

Thirty kilograms of waste plastic of fabriform shapes was used as a partial replacement for sand by 0%, 10%, 15%, and 20% with 800 kg of concrete mixtures. All of the concrete mixtures were tested at room temperature. These tests include performing slump, fresh density, dry density, compressive strength, flexural strength, and toughness indices.

Answer (1 of 4): Stone dust - if you are talking about the finer particles than 150 micron - it is not recommended to use in concrete. Almost everywhere, concrete is done using crush stone sand. Cement is normally passing through 90 micron. Dust have particles finer than 90 micron. Some have ...
