Stress Due to Alkali-Silica Reaction in Mortars

Stress Due to Alkali-Silica Reaction in Mortars- A test method and test apparatus is presented. It does not measure the length change but measures the stress generated by the swelling of the gel. The force required to prevent expansion is measured over time while the specimen and frame are immersed in a solution of 1-N NaOH at 50°C. With some test results.
