| المستخلص: | This paper investigated the effect of high elevated temperatures on the compressive and tensile strength of cement mortar fabricated by partially replacing sand (FA) by ground tire rubber (GTR) particles. The percentages by volume of GTR/FA were, 0% 5%, 10%, 15% and 20%. All mortar samples were prepared and cured in tap water for 28 days, then kept in laboratory atmosphere until the beginning of the test. The specimens were subjected to different target temperatures of 100, 200, 300, 400 and 500˚C. After reaching to the desired target temperature, the specimens were sustained at desired temperature for 2 hours. After heating, the specimens were allowed to cool at room temperature until the date of the test. The results showed that all mortar specimens exposed to high temperature suffered a significant decrease in both compressive and tensile strengths. The optimum GTR% which gave the highest relative compressive strength was in the range of 5% to 10% while that gave the highest relative tensile strength was in the range from 10% to 15%. The mass loss increased with increasing of temperature up to 500˚C and GTR%. In addition, at high temperature 500˚C it was noticed that no cracks appeared on the surface of specimens. |
