Abstract
On the basis of experimental results, the study shows that the use of dynamic modulus of elasticity and ultrasonic pulse velocities is not valid for judging the quality of concrete in which alkali-silica reaction has occurred. As alkali-silica reaction progresses, the constitution of concrete gradually changes in respect to the proportions of crystalline and noncrystalline materials by the latter becoming greater. It implies that concrete become more viscous. Because of this, it is concluded that dynamic modulus of elasticity and ultrasonic pulse velocity are very insensitive indicator of the level of deterioration of ASR affected concrete.
