摘要
An investigation is reported on the influence of exposure temperature on the chloride diffusion properties of 7 widely used surface treatment systems for concrete. The variation in dry film thickness, based on the manufacturers recommended application rate, is measured. Chloride diffusion is determined for both treated concrete and standardised sintered glass substrates. It is shown that whilst all surface treatment systems perform best at low and medium exposure temperatures, the chloride flux through treatments applied to concrete and sintered glass substrates differs greatly. Based on this study, a tentative classification of the surface treatment systems for different exposure temperatures has been developed.
