Resumen:

This paper analyses the economical and environmental viability of the use of stainless steel reinforcement in structural members subjected to aggressive environments like wastewater. Analyses are based on the comparison of a reinforced concrete wastewater tank using conventional carbon steel or stainless steel, regarding environmental and economical aspects. The use of corrosion resistant reinforcement allows: smaller coverings, greater crack width limits and smaller cement quantities, which reduces the global cost. Although water tightness does not allowed relaxing the crack width, stainless steel reinforced tank global cost is reduced to twice the cost of the carbon steel one. Two favourable aspects of the use of stainless steel were disregarded: maintenance costs during service life and a possible relaxation of the crack width limit when using stainless steel. © 2008 Taylor & Francis Group, London.
