摘要：
Sticky rice-lime mortar has great application potential in repairation of Chinese heritage sites. The reinforcement of site soil has been certain influenced by the temperature of glutinous rice slurry. Therefore from the temperature point, the control index of making glutinous rice slurry is investigated. The aim is to save time and gain the desired glutinous rice slurry with obvious reinforcement effect. From the aspects of hardness, longitudinal wave velocity and unconfined compressive strength, the performance of site soil reinforced by glutinous rice slurry can be superior between 75℃ and 80℃. When the concentration of glutinous rice slurry equals to 6%, the reinforced site soil has larger hardness, longitudinal wave velocity and unconfined compressive strength. Cured five days under natural environment, the hardness of sample surface basically tends to be stable. Finally, based on the viscosity, physical and chemical property of glutinous rice slurry, the test results has been explained reasonably. © 2017, Science Press. All right reserved.
