<p>A building element is produced by way of first mixing a mineral binding agent with small grains sized 0.5-1.5 mm of expanded volcanic silicate sand (THERMOSILIT) and then mixing the achieved cast compound with larger pellets of expanded and sintered clay (LECA) and casting an air-proof element of the mixture. Thereby an element is achieved which is air-proof, has low density, high compression strength, low diffusion resistance, and high thermal transmittance resistance.</p> |
