Perspective Technologies for the Disposal of Spent Adsorbents Based on Zeolites in Building Materials

Abstract

This paper presents the results of investigations and substantiation of the possibility of disposal of spent adsorbents created on the basis of the modification of natural zeolite tuffs of the Holinsky deposit of East Transbaikalia, and used in industrial wastewater treatment technology, in building materials are presented. Effective technological methods of using zeolites and zeolite-like materials are considered: non-firing technologies (an extensive class of mixed binders), concretes, autoclave-free silicate products, ash-zeolitive compositions; firing technologies (high-temperature: 1100-1200 °C artificial porous aggregates), ceramic materials of a wide range of applications, aluminosilicate component in the preparation of Portland cement clinker and binders, foams.
