On May 10, NRMCA’s Karthik Obla presented a webinar titled Selecting Exposure Classes and Requirements for Durability offered through Structure magazine, published by the National Council of Structural Engineers Associations. More than 1,300 specifying engineers had registered for the event. 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 a licensed design professional. NRMCA has developed some simple resources that will help designers select the appropriate durability exposure class and corresponding concrete requirements. The presentation discussed the durability requirements of the code and involved a demonstration of the NRMCA resources. The webinar was sponsored by NRMCA’s Build With Strength initiative.
