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.

3. Hardening and Binding. Yet another huge difference is that because polymeric sand contains binders such as cement, when mixed with water, it hardens into one monolithic substance. On the other hand, stone dust contains no such binders and does not harden. That dust does not adhere to itself or anything else. 4.
