Method of manufacturing a porous structural element

摘要

The porous construction component (1) is of calcium silicate hydrate (CSH) together with perlite, with a bulk density or 50-400 kg/m3 or 75-200 kg/m3 or 90-140 kg/m3. External pressures are applied to the surface, to give irreversible distortion and form shaped structured (3,5). The applied pressure is at least0.04 N/mm2 or at least0.8 N/mm2 or at least1.0 N/mm2. The porous component has a thermal conductivity of at most0.08 W/mxK or at most0.05 W/mxK.
