Abstract:

Modern infrastructures are designed for long service life and are increasing being built in more aggressive greenfield and brownfield areas. Sulfate, acid-sulfate and acid resistant concrete are engineering solution to these challenges in infrastructures without the need for additional protective membrane associated with conventional concrete. This paper presents an experimental investigation on mechanical properties of concretes made from a new acid-resistant mortar and a conventional concrete, and corresponding reinforced concrete beams, subjected to accelerated acidic environments in UTS laboratory. Concrete properties including compressive strength, modulus of elasticity, mod ulus of rupture, indirect tensile and drying shrinkage were examined. The load carrying capacity of companion reinforced concrete beams were determined. The specimens were tested before and after periods of exposure to sulphuric acid solution with the concentration of 7% and changes of their properties were evaluated. The results enable an understanding of the mechanism of acid attack and the benefit of the use of acid resistant concrete. On the other hand, the effect of acid attack on reinforced concrete beams is highly dependent on the design of the reinforced concrete beams and to a less extent on the acid resistant property of the concrete.
