RILEM Test Procedure
The RILEM test was developed to measure the effectiveness of water repellent admixtures, such as Impede IntraSeal. The procedure consists of adhering a 5 ml open-ended beaker, called a RILEM tube, to the concrete with putty ensuring a watertight seal. The water is allowed 1 hour to penetrate the concrete. After 1 hour, the water level is recorded to determine the amount of water that has penetrated the concrete.
RILEM Test Results
|Control initial water 5ml full||Impede IntraSeal initial water 5ml full|
Control after 1 hour
Impede IntraSeal after 1 hour
|After 1 hour, Control lost 2 ml of water to absorption. After 3 hours all water had penetrated the concrete.||After 1 hour, Impede IntraSeal treated concrete has no water loss to penetration. After 7 days, still no absorption.|
