MECHANISMS OF WATER ABSORPTION BY CONCRETE . PROTECTION OF CONCRETE. PROCEEDINGS OF THE INTERNATIONAL CONFERENCE HELD AT THE UNIVERSITY OF DUNDEE, SEPTEMBER 11-13, 1990

Data from a literature survey on the absorption of water by concrete are presented, together with the main results from some experimental work on water absorption. The literature survey highlights a diversity of approaches, in both the understanding of the basic concepts and the mathematical solutions. The capillarity approach for unsaturated conditions and the permeability approach for saturated conditions are discussed and compared. The concept of sorptivity associated with water flow in unsaturated concrete is also discussed, together with the variety of definitions found. The experimental work is associated with the measurement of the absorption of water by samples of concrete of different thicknesses. Absorption through both cut and as cast surfaces is investigated. The results are presented in terms of weights of water absorbed and distances of penetration. It is suggested that the sorptivity of cover concrete will give a better idea of the rate of water absorption than its permeability. (Author/TRRL)
