Utilization of glass cullet for the manufacture of binding material used in the production of concrete

Utilization of secondary raw materials and waste materials in construction allows us to reduce building costs and to improve ecological situation. One of the most abundant wastes is glass cullet, which cannot be totally utilized nowadays by means of the existing technologies. In the given research work the methods of manufacture a binding material on the basis of glass cullet are discussed. The material can be used for the manufacture of monolithic structures, similar to concrete ones. It have been discovered that amorphous silicon dioxide can interact with Na+ ions, which results in formation of new phases in the system and strengthening of the composition. Mixtures of dispersed glass with amorphous silicon dioxide were tested by various methods. The conditions for obtaining strong binders on the basis of dispersed glass have been developed. As a result, glass concrete with the compressive strength up to 50 MPa has been obtained.
