Manufacturing Sand And Aggregates For Concrete In Nigeria

Using Recycled Aggregates for Concrete

15-09-2020· In its appraisal, concrete produced from recycled sand and aggregates is unfairly pitted against higher-strength concrete produced using aggregate, such as granite or basalt, and natural sand. It is fair to say that not all granite or sandstone deposits display the same strength characteristics and therefore selective end-use logic is applied.
