In order to improve the bonding performance between the mortar bedding layer and the interface of precast concrete piers and bearings, a layer of interface agent was painted at the joint, and the effect of silica fume admixture on the bonding performance of the interface of precast concrete was studied with different silica fume admixtures as the reference, and the flexural strength, compressive strength, tensile strength and shear strength were tested respectively. The results showed that the flexural and compressive strengths increased and then decreased with the increase of silica fume dosage at the same age, and the flexural and compressive strengths were the highest at 8% of silica fume dosage, which were 9・ 5 MPa and 63 ・ 6 MPa, respectively・ The 28 d strength values were 1・ 7 MPa and 1・ 65 MPa at 8%, which showed the best adhesion performance, and the 28 d strength growth rate increased by 40% and 65% respectively compared with 7 d・ The mechanical properties and adhesion performance were analyzed comprehensively, and it was concluded that the interfacial adhesion effect was the best at 8% of silica fume.
