Pomical
Composition*
POMICAL 0-8 and 0-14
RECONSTRUCTED PARTICLE SIZE DISTRIBUTION CURVE OF PUMICE FOR LIGHTWEIGHT NON-STRUCTURAL CONCRETE
POMICAL is a mixture of Pumice (alveolar product of remarkable lightness and high insulating properties resulting from the natural expansion of effusive magmatic mineral) with a particle size distribution curve of 0-8 mm or 0-14 mm, used in the production of lightweight thermo-insulating and soundproof concret e with a low specific weight and is easily pumped. This is an ecological product that contains no Free Crystalline Silica.
POMICAL FOR STRUCTURAL USE 28 and 44
RECONSTRUCTED PARTICLE SIZE DISTRIBUTION CURVE OF VOLCANIC INERTS FOR LIGHTWEIGHT STRUCTURAL CONCRETE
POMICAL FOR STRUCTURAL USE in the two formulations 28 and 44 is a mixture of alveolar volcanic inerts of remarkable lightness and high insulating properties resulting from the natural expansion of effusive magmatic minerals with a particle size distribution curve of 3-10 mm used in the production of lightweight thermo-insulating and soundproof structural concrete with a low specific weight and is easily pumped. This is an ecological product that contains no Free Crystalline Silica.

MIXTURE OF VOLCANIC AGGREGATES FOR STRUCTURAL CONCRETE
Europomice identified in Pumice and Lapillus products able to meet the new needs of the construction industry: lightness, absence of silica free, high thermal and sound insulation, fluid retention, make these volcanic aggregates of efficient substitutes for polystyrene, expanded clays and other similar materials. Pomical for Structural Use in its two formulations 28 and 44 among other does not require machining prior to use and maintains high characteristics of pumpability and workability, even in extreme conditions.
