ASCE Seattle Section Ports and Harbors Committee Monthly Dinner

Precast/prestressed concrete is the preferred material in many marine applications, providing an economical solution with inherent long-term durability. Concrete Technology Corporation has been an active participant in this market for over six decades, providing products for fixed piers, floating structures, marina floats, and miscellaneous marine applications. This presentation will provide highlights of precast concrete products, materials, and methods including:
Profiles of various fixed and floating structure projects and product types used.

Discussion of the typical concrete and reinforcing materials used in marine applications, as well as discussion of less typical materials to consider in special applications (i.e., self-consolidating and modified-density concretes, or supplemental cementitious materials).
Illustration of the production cycle of a product moving through the manufacturing process, the tooling and equipment required for prestressing, and the impact the daily production cycle has on materials and methods.
Practical guidelines for owner requirements for special material testing, such as alkali-silica reactivity and rapid-chloride permeability testing.
