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).

Introduction In the 1920s and 1930s, several buildings in California, the US developed a major breakdown in a matter of years. In 1940, Stanton showed that this was mostly due to the expansion of the alkaline aggregate. Another expansionary deterrent, called the alkaline-carbonate reaction, was reported by Swenson in 1957. ------------------------------------------------------------------------ * Corresponding author.
