Coastal and Floodplain Construction Inspector's Practice Exam

Concrete exposure classes are determined in accordance with the durability requirements of which code?

1. ACI 350

2. ACI 318

3. ACI 301

4. ACI 224

The correct answer is: ACI 318

Concrete exposure classes are primarily determined in accordance with the durability requirements specified in ACI 318. This code focuses on the structural concrete design requirements, including considerations for environmental conditions that affect the durability of concrete. By outlining the various exposure classes, ACI 318 addresses the necessary measures to ensure that concrete remains durable against factors such as moisture, temperature extremes, and chemical attacks. The answer highlights the critical nature of understanding different exposure classes to ensure appropriate material selection and implementation practices that enhance the longevity and integrity of concrete structures. While other codes such as ACI 350, ACI 301, and ACI 224 offer valuable insights into specific areas of concrete applications and crack control, they do not serve as the primary guide for determining exposure classes in the context of durability requirements within structural design.
