scope:

This guideline offers recommendations for the use of Portland cement concrete in the use of mechanical draft cooling towers. The contents are applicable for towers, basins and auxiliary structures of both cast in place and precast concrete construction, except for prestressed construction. Erection methods are not covered in these guidelines, and any construction loads applied to structural members must be included in the design.

Recommendations for service in fresh and brackish/seawater environments are offered in this standard in Table 1. Technical requirements for design and construction in high sulfate, chloride or other aggressive environments should be referred to design consultants experienced in concrete design for special environments.

The technical recommendations outlined in this guideline are primarily to assure that the concrete designed and used in mechanical draft towers possess characteristics for adequate durability. Requirements for the design strength of the concrete, reinforcing steel and other parameters should be referred to licensed professional engineers familiar with the design and erection of cooling towers.
