| contents | This study experimentally investigates the influence of CaCO3 polymorphs on the thermal conductivity (TC) of biocement and biocemented sand. Calcite-rich biocements consistently showed higher TC than vaterite-dominated ones, regardless of density or saturation. Vaterite-rich biocement, resulting from rapid precipitation and elevated organic content, yields inherently lower TC. This study shed light on the limited TC improvement observed in vaterite-rich biocemented sand. |
