【 摘 要 】

Abstract The present study focused on the characteristics of lime-tile dust mortars with sticky rice addition, which were prepared according to historic Chinese accounts. Results showed that addition of sticky rice into mortars could improve water retention capacity, prolong setting time, and reduce bulk density values. Sticky rice addition also had long-term detrimental impacts on mortar strength development, concurrently increasing their water absorption values. FTIR, XRD and TG-DSC analyses revealed that the addition of sticky rice into mortars could slow down the carbonation as well as hydration process, at the same time forming both calcite and aragonite as carbonation products.
