· The system produces sand for normal concrete and sand for RCC. The biggest difference between the two types of sand is the different content of stone powder, which is 6-18% in the former and 12-18% in the latter. In the process, the following measures are mainly adopted to control the quality of the two finished sand:
· As "basalt powder" is usually understood a fine waste stream from basalt processing (crushing, cutting, etc.). ... promising results in terms of durability were obtained when 10 % of basalt powder was used instead of a part of the cement, and 40 % of basalt sand was utilized to replace fine aggregates. Nevertheless, to our best knowledge ...
