Effects of sticky rice addition on the properties of lime

Jan 07,  · 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
