A review is presented of the work carried out in the author’s laboratory over the past ten years concerning the fire endurance of concrete masonry walls. After defining fire endurance, the author surveys the material properties of concrete and the geometric features of the component units that affect the performance of concrete masonry walls in fire. Empirical and semi-empirical formulas are presented that not only provide means for predicting the fire endurance of these walls but also serve as bases for deriving rules for the correct design of concrete masonry units. A numerical example is included to illustrate the application of the formulas. Lightweight aggregates are included along with normal-weight aggregates.
