Hydrothermally cured pore or foam concrete material, hydrothermally cured pore or foam concrete molded body, process for its preparation and use of precipitated calcium carbonate and / or calcium magnesium carbonate

摘要

The present invention relates to a hydrothermally hardened pore or foam concrete material comprising a solid web framework which surrounds pores resulting from a foam or generated by a blowing process, the solid web framework having calcium silicate hydrate phases, micropores and at least one inert additive, the solid web framework being precipitated as calcium carbonate and an inert additive / or has precipitated calcium magnesium carbonate and / or chalk, as well as a method for producing the pore or foam concrete material and the use of precipitated calcium carbonate and / or precipitated calcium magnesium carbonate and / or chalk as an additive in the production of the pore or foam concrete material.
