Abstract
Investigation on Effect of Aggregate Type on Velocity of Ultrasonic Waves

( Received: 2013/8/3 - Accepted: 2013/11/20)
Abstract Use of the investigation on microstructure, have advantage that recognition on void and denser and durable and higher strength on concrete accorded. In this experimental study, investigated on compressive strength and velocity of ultrasonic waves and microstructure of interface transition zone on concrete with use of aggregates type of sillces, dolomite, limestone and granite on age of a polestar. By using of the Ultrasonic and Scanning Electron Microscope (SEM)set studied on microstructure on interface transition zone of concrete. The result shows the stuff of aggregate effect on compressive strength and so, the role of its on microstructures and thickness on interface transition zone. With increase of thickness of interface transition zone the velocity of ultrasonic waves on concrete decreased.
Keywords: Aggregate Type, High Strength Concrete, Microstructure, Interface Transition Zone, Ultrasonic Waves
