Light weight concrete mixture - comprises fragmented granulate foam mate-rial filler instead of sand

摘要

Light weight concrete mixture contains as one constituent spheroidal granules of foam concrete of shale and instead of sand fragmented spheres of the above material broken up into as large pieces as possible. Components made from this mixture have a greater green strength than those made from sand containing concrete mix. This helps the handling of the partially set components when they are removed from their moulds.
