Concrete structures that are expected to last a long time in a severe environment must be built with proper attention to design, materials selection and proportioning, and construction practices. This paper addresses the construction issues, including placement and curing of concrete. In placement, the importance of cover depth, effects of pumping on air content, need for properly functioning vibrators and screed, and the consequences of improper consolidation are described. The necessity of proper curing is addressed by explaining cracking that result from loss of moisture. The variation in strength between that of the test samples and that of the member is described for concrete subjected to steam curing.
