Variation of flexural strength of cement mortar attacked by sulfate ions

摘要：

Under the environment of seawater, durability of concrete materials is one of the chief factors considered in the design of structures. The decrease of durability of structures is induced by the evolution of micro-damage due to the erosion of chlorine and sulfate ions,which is characterized by the reduction of modulus, strength, and toughness of the material. In this paper, the variation of the flexural strength of cement mortar under sulfate erosion is investigated. The results obtained in present work indicate that the erosion time,concentration of sulfate solution, and water-to-cement ratio will significantly affect the flexural strength.
