Self-sealing property of concrete—Experimental evidence
Abstract Leak-tightness of concrete is often judged in terms of the D'Arcy coefficient determined by the flow of water through saturated concrete at a constant rate. In the case of flow through saturated concrete, this rate often reduces with time and reaching a constant value may take many days. The present experiments were designed to explore various models in order to account for this behaviour. The results obtained support the concept that the dissolution and redeposition of alkalis is the most significant mechanism in the time-dependent reduction of flow of water in saturated concrete. Permeability of saturated concrete and self-sealing may be used as measures of the “immune” systems and potential durability of different concretes.
