Structural lightweight concrete is preferably produced in a compulsory mixer. If possible, the mixer blades should have a plastic lining in order to avoid unnecessary crushing of the LWA, especially in the case of very light LWA. In concrete plants, up to 5–10% of the very light coarse LWA can be crushed.
