WHY USUAL SPECIFICATIONS DO NOT PRODUCE DURABLE CONCRETE . PROCEEDINGS OF 3RD INTERNATIOAL CONFERENCE ON DETERIORATION AND REPAIR OF REINFORCED CONCRETE IN THE ARABIAN GULF, BAHRAIN, OCTOBER 21-24 1989. VOLUME 1.

This paper addresses the question of why durable concrete is not produced insofar as protection of steel reinforcement is concerned. Special reference is made to the Arabian Gulf area. Existing specifications have led to a deterioration of numerous structures in the Arabian Gulf area. In particular, reliance on compressive strength and minimum cement is insufficient to prevent corrosion of reinforcement under exposure to chlorides. A large cover is effective only if the cover concrete has a low penetrability. This requires the use of superplasticizers and, under extreme conditions, of hydrophobic and pore-blocking additives. Even with all these measures, really good curing is essential. The disadvantages of the use, under some conditions of exposure, of sulphate resisting Portland (Type V) cement and of fly ash (pfa) and ground granulated blast furnace slag are discussed. For the covering abstract of the conference see IRRD 828897.
