A Concrete Frost Scaling Mechanism by Exposed to Deicing Chemicals With Dilution Water

Abstract

：Frost scaling damage to concrete structures is affected by complex combinations of multiple factors. Therefore concrete scaling mechanism is not yet completely understood. This study examines concreteʼs damage exposed to deicing chemicals within dilution water. The existence of the dilution water is greatly connected with salt frost damage. The neural networkʼs analysis is effective for clarification of the relationship among complicated factors. This study revealed an important relationship between scaling damage and dilution water. A scaling damage evaluation was confirmed using a thermographyʼs technique. And concrete surface irregularity is grasped by three-dimensional photograph digital measurement systems.
