Studying Sulfo-Aluminate Cement-Based Pavement Repair Materials'Physical and Mechanical Properties
Through indoor tests,the effects of various types of admixture mixing ratios on the mechanical properties,bond strength,and dry shrinkage properties of cement mortar repair material are examined in this paper,which uses special sulfoaluminate cement as the cementitious agent of cement-based pavement repair material.It was discovered that the ideal proportion to increase the flexural and compressive strength of ce-ment mortar was 2.5％gypsum and 1.25％gum powder;Surface roughness and bond depth both boost mortar bond strength.A large amount of variability in the drying and shrinking characteristics of sulfoaluminate ce-ments can also be caused by admixtures.
