Abstract
Wide laboratory search was done to evaluate brick units in single, and test the prisms built from brick unit by use ultrasonic waves in non-destructive test. The results show that the pulse velocity increases with increasing compressive strength and time of construction. From this paper we can estimate compressive strength for building unit by find the equation of the curve ,then we can estimate compressive strength for building sample, for example bricks from pulse velocity of ultrasonic waves without need destructive test.
