Project Details

Project Description: 

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.

Goals

The key project objective is to develop an accelerated Nondestructive Evaluation (NDE) laboratory test method for evaluating concrete mixtures for alkali-silica reactivity (ASR).
