SP8 A collection of 10 papers on various aspects of the construction of concrete waterfront structures, concrete waterholding structures, and concrete construction in aqueous environments, Covers tremie concrete, prestressed tanks, concrete piles, joints and cracks, concrete pontoons, effect of sea water, and pier design.

Discusses the design, consiruction, and maintenance of prestressed concrete tanks by East Bay Municipal Utility District, Calif., and describes improvements in design and construction procedures.

Prestressed concrete cylinder piles are especially suitable for substructures of viaducts, grade separation structures, and bridges because they function simultaneously as foundation piles and structural members. Their design, fabrication, and installation is described.

Presents some of the rules and lessons learned from experience, as well as analyzing a few of the difficulties and problems encountered, in the placement of high quality concrete under water by the tremie method.

The three main causes of deterioration in concrete, freezing and thawing, reinforcement corrosion, and chemical attack by sea water, are discussed on the basis of the fundamental concept that these causes can be generally minimized if watertight concrete is attained.
