Webcapillary attraction n. The force that results from greater adhesion of a liquid to a solid surface than internal cohesion of the liquid itself and that causes the liquid to be raised against a vertical surface, as water is in a clean glass tube. It is the force that allows a porous material to soak up a liquid. WebReduces the capillary attraction of the voids in the concrete and decreases water absorption of concrete or mortar.
