Differences in ASR Experiments Between the Short and Long Term Test Methods

Abstract

The main objective of this study is to compare the effect of alkali-silica on concrete from a previous experiment by Stanton in the forties of the last century, which was the basis for researchers to investigate and study the extent of alkali-silica reaction against concrete, by various methods for testing the reaction of alkali-silica. From that point on, scientists have tried to develop testing techniques that can be used quicker to detect the effect of alkali-silica on concrete, and 16 alkali-silica testing methods have been highlighted in this study both in short and long-term terms. These methods have been chosen at random but the chronology and most of their details, how they have been performed, the materials used in this test, etc. have been determined. In the same way, the results of the test methods were explained and the available studies, research, and specifications were followed. Finally, the selected test methods have been compared and the parameters used to compare the test methods were as follows: duration, temperature, specimen size, mix type, used materials, admixtures, water/cement ratio, and expansion limit. The comparison took three forms, the first was a comparison between short-term methods alone and the second was a comparison between long-term methods alone, while the latter was between the two method types using standard concrete practices for civil work structures (EM 1110-2-2000).
