摘要
A method for activating and/or accelerating the setting of a non-refractory, hydraulically setting paste material (A), selected from concretes, mortars and cement pastes, involves applying ultrasonic vibrations to (A), optionally after the setting of (A) has been retarded by addition of a retardant (I). An independent claim is included for a device (no description given) for carrying out the process.
