Study on the Resistance of Marine Silica-Fume Concrete between both Frost-Thaw Cycles and Chloride Penetration (Part I)

Article Preview

Abstract:

A study was made into the resistance in frost-thaw cycles and chloride penetration of silica-fume concrete by simulating the characteristics of the marine environment and using the R-value evaluation method. The results show that as a result of mixing silica fume in concrete, the R-value increases by 52.1%; the composite use of silica fume and air-entraining agent with an adequate mixing amount can increase substantially the comprehensive property of concrete in resisting frost-thaw cycles and chloride penetration, with the magnitude of R-value increase being as high as 174%~ 284% and the silica mixing amount being best at around 10%.
