Abstract:
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.

Two series of lightweight concrete mixes made with expanded shale and slag aggregates were prepared for heat exposures between 300 C and 1000 C (572 F to 1832 F)/ To some concretes microfillers such as fly ash, silica flour, and calcined shale dust were added to replace 25 and 40% of the portland cement in the binder.

An investigation is discussed which had as its aim the clarification of the causes of strength loss in heat cured concrete as compared with normally cured concrete. It is concluded that the dominant causes are of a physical nature, i.e., increased porosity and cracking, which can be the result of the pressure which occurs in the air pores upon heating. Criteria for the occurance of cracking have been formulated and with the aid of these the minimum tensile strength necessary to avoid cracking can be determined.
