Perlite aggregate consists of expanded perlite sized for use in lightweight fire retardant insulating concrete ‘’GULF PERLITE CONSTRUCT’’ in place of sand or gravel. For easy handling and accurate on–the-job mixing, it is available in water and UV proof bags of 100 l capacity ready for use. The many, tiny glass - sealed cells in each particle of expanded perlite make it highly insulating as well as comparatively non - absorptive. Thus perlite mixes with about 40% less water than comparable lightweight aggregates.
