The products includes five series: crusher, sand making machine, powder grinding mill, mineral processing equipment and building materials equipment.Test results showed that the compressive strength of the concrete decreased as the content of ceramic waste present in the concrete increased. Thusconcrete produced from the partial replacement of ordinary Portland cement with ground ceramics gave compressive strengths of 16.6 Nmm2 and 13.4 Nmm2 at 5% and 20% replacement levels respectively..
