Muhit et al. determined that passing from 200 mm sieve is used as cement replacement whereas retaining from 100 mm sieve is used as sand replacement. Cement was replaced with stone dust in percentage of 3, 5, and 7 percent. Similarly, sand was replaced with stone dust in percentage of 15 to 50 with an increase of 5 percent.

The results of the tests show that stone dust may be utilized in concrete as a partial replacement for fine aggregate. The finding has been made that using stone dust increases the flexural and compressive strength of concrete. The percentage of fine aggregate replaced by stone dust (0, 20, 50, 80, and 100 percent) is explored.
