Non-Autoclaved Lightweight Concretes Based on A Nano-Modified Dry Mix for Foam Concrete
Allanazar Ilyasov , Karakalpak state university, Uzbekistan Raman Auezbaev , Tashkent state transport university, UzbekistanAbstract
In this study, a dry foam concrete mix was nano-modified, and based on it, foam concrete compositions were developed using lightweight porous aggregates—expanded clay gravel, foam glass, and polystyrene granules. It was experimentally determined that the introduction of silica sol in an amount of 0.001% relative to the cement mass resulted in an average increase of 15% in the compressive strength of the foam concrete. The developed foam concretes with porous aggregates are intended for thermal insulation and structural applications, with their average density formed in the range of 300 kg/m3 to 750 kg/m3. Research results showed that these foam concretes have a structural quality coefficient that is 30% or higher compared to foam concretes without aggregates, and they have the potential for effective application in the climatic and construction conditions of Uzbekistan.
