Restrained Alkali-Aggregate Expansion of Concrete due to External Wrapping and Its Mechanism
The alleviation of alkali-silica reaction (ASR) in existing concrete structures is a complex problem. This paper introduces some experimental research on this issue. Results and analysis show that ASR can be alleviated in small concrete specimens by wrapping with fiber reinforcing polymers. The higher the Young's modulus of fiber, the better the alleviating effect is. Sufficient thickness of FRP and three-dimensional wrapping should be provided. Theoretical analysis shows that waterproofing is the primary reason that FRP-wrapping suppresses ASR. Physical restraint is a secondary mechanism.
