Building Solutions with Alkaline activate Binders
Objective. Comprehensive studies of ancient concretes have established the presence in them of zeolite-like minerals, which are analogues of naturally occurring compounds containing alkalis. The work presents development of research aimed at obtaining compounds similar to existing minerals of the earth's crust, and encourages researchers to develop alkali binder systems to use the best results during repair and restoration work of historical architectural objects. During the experiment, such important properties for repair compositions as density, ductility, adhesion, viability and strength were studied.Method. The studies were carried out in accordance with regulatory documents GOST 12730.3–2020 Concrete. Methods for determining water absorption; GOST 5802–86 Construction mortars. Test methods; GOST 31356–2013 Dry building mixtures based on cement binder. Test methods.Result. The results obtained correspond in their technical characteristics to products based on Portland cement, the mortar grades were achieved in terms of strength M75–150, in terms of mobility Pk1 and Pk2, viability sufficient for carrying out repair and plastering work 33 minutes – 1.5 hours, high adhesive strength 0.62–0.72 MPa.Conclusion. The compositions of mortar mixtures will allow high-quality performance of a variety of work: repair, plastering, finishing. The stable properties of the components, strict adherence to the compositions and production technology of mixtures will make it possible in the future to synthesize nature-like and durable minerals in the structure of a high-quality and durable material.
