At present, a tendency to substitute hazardous organic adhesives in the majority of building materials is clearly observed. This is connected with the more strict than before requirements for health safety, fire safety and durability. The most important task is substitution of organic binders, traditionally used as adhesives for gluing concrete, brick and ceramics with non-hazardous inorganic binders. To solve this problem an adhesive for concrete, brick and ceramics based on ecologically friendly alkaline aluminosilicate binder (geocement) has been developed. This binder is itself an inorganic polymer, which combines properties of inorganic substances (high strength and frost resistance) and those of organic substances (elasticity, adhesion to various materials etc.) and is analogue to alkaline aluminosilicate materials occurring in nature: zeolites, feldspathoids, etc. Bonding strength of the geocement-based adhesives to various surfaces is higher than 1 MPa. With taking into account high pH of the geocement stone a proper choice of fillera and additives is important. The purpose of the study was to reveal influence of the geocement-based adhesive composition on properties and, accordingly, on structure of the interfacial transition zones: "concrete-concrete", "concrete-ceramics", "ceramics-ceramics".
