Pre-soaking Lightweight Aggregate for …

Concrete containing lightweight aggregate can experience severe slump loss during pumping if the aggregate isn't wet enough. Because of this, some producers of lightweight aggregate use vacuum or thermal processes to saturate their material. The amount of water absorbed during these processes may be two or three times that absorbed in 24 hours under atmospheric pressure. These aggregates can ...
