Using Ultrasonic Wave to Study Modulus of Elasticity, Shear Modulus and Poissons's Ratio of Polymer Concrete.

Abstract

The main aim of this study is assess the modulus of elasticity , shear modulus and Poissons's ratio of polymer concrete (PC).Polymer concrete is a composite material realized with resin and aggregates.The Unsaturated polyester composite  resin was used for binding the aggregates. The silica foam and  glass fibers were introduced in the composition as filler.Some mechanical properties of polymer concrete have been investigated, by non-destructive method. The experimental results of ultrasonic wave at 26 KHz test were correlated with, modulus of elasticity, shear modulus and Poissons's ratio. The fiber percentage and silica foam was constant, the unsaturated polyester resin and the Silica sand dosages were varied.The results showed that by increase the percentage of sand aggregate (%W) in all groups the Poissons's ratio,Pulse Velocity,Modulus of Elasticity and Shear Modulus are increased.
