Permeability and pore size distribution in medium strength self-compacting concrete
The use of self-compacting concrete (SCC) has been on the rise in recent years. Research on this type of concrete has focused primarily on determining optimal dosage, while durability, particularly for medium strength SCC, has received much less attention. The present study explored the permeability of a number of medium strength (characteristic strength, 30 MPa) self-compacting concretes, including SCCs made with common cement, in pursuit of a balance between performance and cost. Pressurised water and mercury intrusion porosimetry tests were conducted to determine concrete behaviour when exposed to aggressive agents. The findings showed that the capillary networks of these concretes are essentially impermeable to aggressive agents.
