- Microbial Induced Calcite Precipitation (MICP) is a technique used worldwide to stabilise geotechnically problematic sandy soils. Here we introduce dolerite fine as an alternative source to calcium chloride required for MICP. Calcium chloride is an industry end-product with significant carbon footprint. Nevertheless, dolerite fine can be acquired as a quarry by-product with marginal carbon footprint. This research is of particular importance to engineering industry sectors internationally focusing on using MICP to treat earth-filled embankment dams and oil/gas-producing wells. Using dolerite as a calcium source would reduce overall cost of MICP and promote wider application of the technique for engineering projects.
