WebApr 23, 2024 · Capillary action, also called capillary filling or wicking, means the spontaneous flow of liquid to fill small capillaries or pores. A famous example is that of capillary rise: when a glass capillary with a small diameter is placed in water, the level of water inside the capillary rises above the level of water outside the tube. WebCapillary porosity is determined by drying a concrete sample and refilling the empty capillary pores with a dense organic liquid. In order to determine original free water/ cement ratio, the capillary porosity of the aggregates must be determined and the result corrected.
