Leaching is the dissolution of some concrete components in a liquid. For example, lime is dissolved according to this reaction : Ca(OH) 2 > Ca 2+ + 2 OH-After leaching, concrete porosity is increased and its deterioration is enhanced. This deterioration remains limited to concrete zones where pure water can circulate (near cracks, etc).
