Options for the implementation of new secondary raw materials in autoclaved aerated concrete

Popis výsledku v původním jazyce

Currently, the only material used as the primary siliceous component of autoclaved aerated concrete (AAC) in the Czech Republic is sand. Within the context of previously conducted research, this article evaluates the use of new types of secondary raw materials to achieve greater economic and ecological benefits during AAC production. The investigated secondary raw materials include fly and bottom ash, slag, and waste glass. AAC composite specimens with admixtures of secondary raw materials were cured by hydrothermal conditions in a laboratory autoclave for 7 and 12 h of isothermal durability 190°C. Of the secondary raw materials tested under laboratory conditions, the highest strength was obtained in the specimen with a 10% waste glass admixture. The other admixture that positively affected the mechanical characteristics of specimens was waste incinerator slag. It is clear from the results of this investigation that the use of secondary raw materials does not diminish strength, but improves mixture rheology and supports the formation of tobermorite.
