AB - The aim of the present paper is to study the mechanical properties of  aluminate cement mortar mixed with different chopped fibers under high  temperature. The specimens with a size of 40 mm × 40 mm × 160 mm is treated  at various tempera­tures of 25°C, 200°C, 400°C, 600°C, and 800°C. The  compressive and flexural strength of the aluminate cement mortar and its  micro-structures are tested. The results show that the chopped steel fibers  and basalt fibers are effective in improv­ing the high temperature  mechanical properties of aluminate cement mortar. When the volume fraction  of chopped steel fibers is 2%, the compressive strength and flexural  strength of the test block treated at the temperature of 800°C increase by  18.3% and 128.6%, respectively.
