Concrete With Aggregate And Crusher Dust

Jun 30, 2011 Thus, CCA—combined with the fine aggregate or “dust” from the crushing process—has a higher demand for water and cement, resulting in the potiental forgreater shrinkage and lower strength. Because the crushing process produces concrete aggregate with jagged edges and dust, the resulting concrete was considered too harsh for applications.
