If the slag is not disposed of in a landfill, it may be used as a secondary raw material in the construction industry, as an additive to cement. In the concrete industry, it is common to use moisture measurement sensors to determine the moisture of individual aggregates. In the production of dry mortar, the drying process can be optimized because the RGI sensor is able to accurately measure only 0.3% residual moisture. This image shows an RGI sensor mounted above the conveyor with a mounting bracket.
