摘要：
According to the physical structure model of low strength cement asphalt mortar (CA mortar), in reference to the particulate reinforcement theories for polymer composites, the quantitative relationship between compressive strength and composition parameters of CA mortar was obtained. Results show that in cement asphalt binder (CAB), the reinforcement effect of hydration product on asphalt focuses on its overall content, and thus Piggott model is suitable for describing the relationship between compressive strength and hydration products volume fraction of CAB. The enhancement effect of sand on CAB focuses on individual attributes, so Nielsen model is suitable for characterizing the relationship between compressive strength and sand content of CA mortar. Verified by the data in the relevant literature, the established model has good universality. © 2022 Cailiao Daobaoshe/ Materials Review. All rights reserved.
