How often must structures made with calcium aluminate refractory structural concrete be inspected?

The requirement for inspecting structures made with calcium aluminate refractory structural concrete every three years is grounded in the material's properties and the performance standards necessary to ensure structural integrity and safety. Calcium aluminate concrete is tasked with handling high temperatures and conditions that can lead to degradation over time, particularly in environments involving thermal cycling or chemical exposure.

Regular inspections help detect any signs of wear, cracking, or degradation that may occur due to the specific stresses placed on the structure. Conducting these inspections every three years allows for timely maintenance and repairs, ensuring the safety and longevity of the structure. This interval is a balanced approach that considers both the durability of the material and the need for proactive maintenance before significant issues can arise.
