The ACI 318, Building Code Requirements for Structural Concrete defines exposure classes and applicable requirements for concrete mixtures used to construct buildings. ACI 301, Specification for Concrete Construction incorporates these requirements in the ACI reference specification. Assigning durability exposure classes is part of the design process and is the responsibility of the licensed design professional. NRMCA has developed some simple resources that will help designers select the appropriate durability exposure class and corresponding concrete requirements. This presentation will discuss the durability requirements of the Code and involves a demonstration of the NRMCA resources.
