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.
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.

A discussion of Canadian research into effects of below normal and above normal temperatures on properties of concrete. The raction of temperature and age on thermal expansion and modulus of elasticity of concrete; vacuum processing; pulse velocity; field curing and protection are covered. Also included are effects of heat applied during curing and after placement, effects of steam injection and review of research by National Research Council of Canada on fire endurance of concrete masonry walls.

This paper reports the relationships of the strength of standard laboratory-cured cylinders to the strength of concrete in 24x24x66-inch (0.61 x 0.61 x 1.68-meter) columns and 24 x 24 x 8-inch (61 x 61 x 20-cm) slabs to that of cylinders cured under exposed winter conditions.
High Early strengths can be achieved by mixing concrete at elevated temperatures.
