Abstract

The possibility to test the use of alternative binders for the production of chemically bonded fly ash aggregate made of low-calcium ash of Kemerovo thermal power stations running on the coal from the Kuznetsk Coal Basin mines is described in this paper. The strength of the granules was taken as the main comparative indicator. The strength was determined by the standard cylinder compression method. The test resulted in the confirmation of the possibility to use the material such as liquid glass for production of chemically bonded fly ash aggregate. Such a change would eliminate cement from the chemically bonded fly ash aggregate production process. Moreover, replacement of the binder will reduce the density, decrease the thermal conductivity and keep the other properties of the material.
