Specialists from the Siberian Federal University (SFU) in Krasnoyarsk have presented a new technology that can significantly increase the strength of glass concrete. This was reported by the Ministry of Science and Higher Education of the Russian Federation.
In addition, this development helps to reduce carbon dioxide emissions during production.
The proposed material hardening technology will allow the use of glass production waste, as well as significantly reduce CO2 emissions during firing in the production of building binder.
The technology is based on mechanochemical activation, which is the process of converting a substance into a more chemically active state through preliminary mechanical processing. The use of thermal and moisture treatment of glass concrete significantly increases its strength.
The composition of glass concrete includes calcined lime, which is calcined at a temperature of 1.1 thousand degrees Celsius. For comparison, the temperature in cement kilns in the production of traditional cement binders reaches 1.5 thousand degrees Celsius. Reducing the calcination temperature of lime helps to reduce the carbon footprint in the production process.
Glass concrete is a modern composite material that is made on the basis of finely ground and coarse glass, calcined lime, water and various additives. It is widely used in construction as a binding component.
