;In order to study the mechanical properties of cement-modified rammed earth materials,8 specimens were prepared according to different particle size and cement content.After 5 years of curing under different curing environments,compressive strength test and apparent durability evaluation were carried out to explore the effects of different particle size and cement content on compressive strength and apparent durability.The results show that the strength of cement rammed earth is related to water content,particle size distribution,cement content,curing method and placement time.The compressive strength of the specimen increased with time accumulation,but the strength of the specimen under outdoor curing for 28 days decreased significantly.The greater the cement content,the greater the compressive strength,and the strength of indoor curing specimen is greater than that of outdoor curing specimen.The apparent durability of the specimen without gravel is good,but the appearance of the specimen with high grave content is poor.
