1. Understand why ACI 350.5-12, “Specifications for Environmental Concrete Structures,” is better suited for specifying liquid-containing concrete structures than ACI 301-10, “Specification for Structural Concrete”.
2. Recognize four different waterproofing products used to detail and construct leak-proof joints for environmental concrete structures and tanks.
3. Identify two methods to construct external prestressed wrapped circular concrete tank core walls: one using cast-in-place concrete and the other using shotcrete with steel diaphragm.
4. Describe the construction process to construct a large liquid-containing circular concrete tank slab, precast concrete walls, and concrete dome structure using ACI 350.5-12.

The contents of this course include three recorded presentations from the ACI 2014 Spring Convention:
1. Overview of ACI 350.5, Specifications for Environmental Engineering Concrete Structures by Charles S. Hanskat, Executive Director/Technical Director at American Shotcrete Association, Farmington Hills, MI
2. Durability and Joints by Kyle S. Loyd, Vice President—Waterproofing, Sika Greenstreak, Saint Louis, MO
3. External Prestressed Wrapped Tanks by Daniel J. McCarthy, VP Engineering & Construction Performance, Preload Inc., Hauppauge, NY

The objective of this course is to provide an overview and details of ACI 350.5-12, “Specifications for Environmental Concrete Structures.” This specification is a reference specification that the Architect/Engineer can apply to a construction project by citing it in the project specifications. The presentations included in this course cover topics such as materials and proportioning of concrete; reinforcement and prestressing; production, placing, finishing, and curing of concrete; formwork design and construction; and shotcrete. This course further discusses two interesting sections in ACI 350.5, Section 4, “Joints and Accessories,” and Section 10, “External Prestressed Wrapped Concrete Tanks.” Both sections discuss critical measures and provide examples (large precast core-wall circular tank) of the design of leak-proof environmental concrete structures.
