Process for producing steam pressure-hardened aerated concrete, in particular gas concrete

摘要

In the production of steam pressure-hardened aerated concrete, in particular gas concrete, about 10 to 42 percent by weight of the binder, containing cement and/or lime, of aggregates, in particular quartz powder, of the fresh waste sludge and of the solid auxiliaries, in each case relative to the dry matter content of these components, in the mortar mixture are replaced by waste comminuted separately (from quartz powder) of hardened aerated concrete (granulated aerated concrete) having grain sizes of less than or approximately equal to 4 mm in diameter.
