Accelerated Determination of Alkali-Silica Reaction Susceptibility During Concrete Prism Testing Through Nonlinear Resonance Ultrasonic Spectroscopy |
摘要: |
The objective of this study is to develop a reliable rapid Nondestructive Evaluation (NDE) technique for assessing and quantifying the alkali-silica reactivity (ASR) in aggregate and aggregate/paste combinations. The American Society for Testing and Materials (ASTM) C1293 test method is accurate, but it takes one to two years to complete. On the other hand, ASTM C 1260 is an accelerated laboratory test method, but its accuracy to predict field performance is not good. |
