PROCESS FOR PRODUCING AUTOCLAVED AERATED CONCRETE USING SILICA RAW MATERIALS HAVING HIGHER SOLUBILITY THAN QUARTZ

摘要

The present invention relates to an autoclaved aerated concrete having a content of tobermorite of at least 12.5 wt% and a content of amorphous CSH phases of at least 30 wt%, based on the total weight amount of autoclaved aerated concrete, the process for producing said autoclaved aerated concrete using a silica source, which comprises a soluble silica species and a low curing temperature and the use of a silica source, which comprises a soluble silica species for the production of an autoclaved aerated concrete.
