Lightweight Concrete Aggregate - Garibaldi Pumice
Garibaldi Pumice produces a lightweight aggregate for concrete products. Use of dacite pumice reduces the weight of concrete products without substantially compromising strength. The final product is lightweight concrete that is strong and durable with excellent insulating, sound dampening and fire resistance capability.
Pumice and Concrete: Lightweight Insulating …
It is the use of pumice aggregate and sand that provide the lightweight advantages of pumice concrete by reducing the dead load on structural supports, trusses, girders and slabs. Pumice is a porous, naturally-occuring volcanic glass, riven with air-filled vesicles formed by the expansion of trapped gasses when the molten lava is expelled into the air and flash-cools.
