The Analysis of the Dual Influences of Sulfates and Alkali Aggregate on the Durability of Concrete

Due to the effect of concrete carbonation,chloride ion corrosion,sulfate attack,alkali aggregate reaction,the service structure was destroyed prematurely,which caused casualties and huge economic losses. The dual factors of sulfate and alkali aggregate effect could aggravate the influence of concrete durability,and the dual factors will interact and influence each other,which increased cracking of concrete. It is the eternal theme in the construction field to ensure and improve the constructional engineering quality. In the paper,based on the actual project as an example,dual influences of sulfates and alkali aggregate on the durability of concrete were studied to avoid the similar accidents,which provided reference for the similar projects.
