Risk Assessment Service Environment.Various factors affecting the sulfate attack of building materials are focused on two areas, one is environmental factor, and the other is properties of materials themselves.
Crack, peeling off, materials like mud on the concrete components with high risk of sulfate attack are key points for inspecting if constructions are located in sulfate environment.
Diagnostic Process for Sulfate Attack of Cement and Concrete Engineering Fig.4.
Conclusions Most of construction engineering must be concern the chemical attack.
