Strength and durability of concrete structures in Bahrain

Abstract

The Bahrain Center for Studies and Research conducted field and laboratory tests to assess the durability and strength of 40 reinforced concrete buildings. Results indicate that the cover over the reinforcing steel in these structures is less than that required by structural codes. Carbonation depth is either nil or very low, and did not reach the steel level in relatively new buildings. Water absorption by concrete is very high due to inferior construction materials and practices and extremely hot environment. Average concrete compressive strength values of recently constructed buildings with superior quality aggregate is 25 MPa, whereas for inferior quality aggregate concrete, the strength value is 14 MPa.
