Abstract:

Note: 350M-01/350RM-01 is available in PDF format only. However, a newer version of this document exists. This document was replaced by 350M-06.

The code portion of this document covers the structural design, materials selection, and construction of environmental engineering concrete structures. Such structures are used for conveying, storying, or treating liquid, wastewater, or other materials, such as solid waste. They include ancillary structures for dams, spillways, and channels. They are subject to uniquely different loadings, more severe exposure conditions and more restrictive serviceability requirements than normal building structures. Loadings include normal dead and live loads and vibrating equipment or hydrodynamic forces. Exposures include concentrated chemicals, alternate wetting and drying, and freezing and thawing of saturated concrete. Serviceability requirements include liquid-tightness or gas-tightness. Typical structures include conveyance, storage, and treatment structures. Proper design, materials, and construction of environmental engineering concrete structures are required to produce serviceable concrete that is dense, durable, nearly impermeable, resistant to chemicals, with limited deflections and cracking. Leakage must be controlled to minimize contamination of ground water or the environment, to minimize loss of product or infiltration, and to promote durability. This code presents new material as well as modified portions of the ACI 318M-95 Building Code that are applicable to environmental engineering concrete structures. Because ACI 350M-01 is written as a legal document, it may be adopted by reference in a general building code or in regulations governing the design and construction of environmental engineering concrete structures. Thus it cannot present background details or suggestions for carrying out its requirements or intent. It is the function of the commentary to fill this need.
