Microbially induced calcite precipitation (MICP) is an emerging soil stabilisation technique consisting of the precipitation of the mineral calcite in the soil matrix. The components required for MICP are currently industry end products. In this study, the calcium release and reusability of calcium-rich silicate quarry fines, dolerite, were investigated in closed

Many quarries also refer to their (sub-economic) fine aggregate (finer than 4 mm) as quarry fines (or quarry dust). The term is used here to denote both fine aggregate and quarry fines (material <63 microns). Quarry fines can be considered a mixture of coarse, medium and fine sand material, and silt / clay (silt and clay is known collectively
