SUPERLIGHT DOUBLE-STRUCTURE EXPANDED PARTICLES AND PRODUCTION METHOD

摘要

The present invention relates to superlight double-structure expanded particles having a density of 40-400 kg/m3 for use as construction aggregate; a method for obtaining the superlight double-structure expanded particles; and a superlight concrete comprising the superlight double-structure expanded particles as aggregate, and a binding agent, wherein the concrete has a density below 350 kg/m3, for producing any light construction element with insulating properties without losing compressive strength, owing to the rigidity of its external structure.
