Abstract

This paper describes modulus of rupture and flexural fatigue testing performed on beam specimens made of Silikal® polymer concrete and course aggregate. Test results indicate that modulus of rupture of polymer concrete increases with increasing rate of loading similar to portland cement concrete. Fatigue test results show good correlation with a mathematical expression relating probability of survival with stress level and number of cycles to failure. This equation was developed and used by other investigators for portland cement concrete. Test results indicate that frequency of loading influences the fatigue life of polymer concrete, but a short rest period within each loading cycle probably does not. Further fatigue study is recommended in the paper.
