Literature review of the use of common protective coatings for concrete structures with experiences in the South African context by Jappie, Luqmaan

“…Process Description Diffusion: Movement of ions, gas or liquid under a concentration gradient Permeation: Movement of a fluid through a concrete matrix under an externally applied pressure gradient when saturated with that fluid Absorption: Where a fluid is drawn into the pores of concrete through capillary suction Migration: Movement of ions due to an electrical potential gradient Combined transport mechanisms and long-term changes in transport behaviour may need to be considered, Additionally, the size, nature and degree of cracking is an especially important consideration (Ballim, Alexander and Beushausen, 2009). …”
