ASTM C1293

ASTM C1293 is a standard test method used to assess the potential for concrete to expand due to alkali-silica reaction (ASR), which can cause cracking and damage over time. In this test, concrete specimens are mixed with specific aggregates and exposed to moisture and temperature conditions that simulate real-world environments. The expansion is measured over a year to determine the material's susceptibility to ASR. This standard helps engineers and builders select appropriate materials to ensure the durability and longevity of concrete structures, ultimately enhancing their safety and performance.
