Structural Concrete — Stalite

In structural concrete, STALITE is proven to be as good as or better than any normalweight aggregate. The unique nature of STALITE's slate raw material combined with the excellence achieved in its production process, results in an extremely high performance lightweight aggregate capable of producing very high strength at low concrete unit weights (up to 30% less than normalweight concrete).

Lightweight concrete

Pumping lightweight concrete can be achieved, but care needs to be taken so that the concrete mix doesn't separate. For pumpable mixes it is usual to use a natural sand, i.e. not to have a lightweight aggregate for the fine portion of the mix and to have a high workability so that increased pump friction and blockage is avoided.
