![]() Store the container at 23 ☒ degrees for a minimum of 15 days at the start of the absorption test.After that, put each specimen in a sealable container, leave a small space between the sample and container wall to allow free airflow around the specimen.Put test samples in the environmental chamber at a temperature of 50 ± 2 degrees and RH of 80 ☓ % for three days.After that, measure the mass of each test specimen to the nearest 0.01 g.Vacuum saturate the drilled core specimens obtained from the field.The test surfaces should be at the same distance from the original exposed surface of the concrete. The test result is equal to the average test result of a minimum of two samples.They should be 100 ☖ mm in diameter and with a length of 50 ☓ mm. Concrete specimens are either drilled cores or molded cylinders.Sealing materials like duct tape or aluminum tape.Top-pan balance, accurate to at least ☐.01 g.Support device, rods, pins, or other devices.The water absorption test aims to determine the rate of water absorption by hydraulic cement concrete.
