Overview

Test steps for water resistance tester: Clean the hole in the middle of the roll material, insert the anti-seepage test piece into the mortar anti-seepage tester. The roll surface should face water, and the surrounding conical surface of the anti-seepage test piece should not be sealed to keep it open to the outside world. Apply pressure to 0.4 Mpa and maintain it for 24 hours. After adding 0.1 Mpa, maintain it for 4 hours until there are water seepage marks on the surface of the mortar test block or until the specified test pressure is reached and no water seepage occurs.

Anti water channeling testerExperimental Procedure:

Clear the hole in the middle of the roll material, insert the impermeability test piece into the mortar impermeability tester. The roll surface should face water, and the surrounding conical surface of the impermeability test piece should not be sealed to maintain smooth communication with the outside world. Apply pressure until0.4MpaMaintain it24hIn the future, every addition0.1MpaMaintain it4hUntil there are water seepage marks on the surface around the mortar test block, or until the specified test pressure is reached without water seepage.

Anti water channeling testerPreparation of test specimens:

Open a diameter in the middle of the coil specimen10mmInsert the hole into the mortar impermeability mold and place it at the end with the larger diameter. The coil should be one circle larger than the sealing ring of the impermeability tester, so that the coil surface can be sealed with the sealing ring of the impermeability tester. Take measures to prevent mortar from being inserted into the hole opened by the coil, and then pour the mortar onto the bonding surface of the coil specimenJG/T245Compaction on the designated concrete vibration table20SThe bonding surface of the roll material is facing the mortar, and the mortar ratio prepared with standard sand meets at least the anti-seepage pressure1.5Mpa, in（20±2）Placed at ℃24hDemoulding and then curing under standard curing conditions28d.
