CONCRETE IN HOT & COLD CLIMATES
The Concrete Society has recently published two guides on concrete in the Arabian Peninsula. The first, in collaboration with CIRIA, deals with the construction of reinforced concrete and the second, in collaboration with the Bahrain Society of Engineers, with the evaluation and repair of concrete structures.
The main durability issues
Steel corrosion is the main cause of reinforced concrete deterioration. Normally, the alkalinity of the concrete around reinforcement provides a passive environment, preventing corrosion. This passive state can be broken down by carbonation of the concrete and/or by the presence of chlorides. Carbonation leads to uniform ...
