Kaminskyi A. Repair mixes with the increased operational properties on the basis of alkaline Portland cement

The dissertation is devoted to solving a task to obtain the operation-enhanced shrink-resistant and expansible alkaline Portland cement-based mixtures for the repair of the concrete and masonry structures distinguished by their high durability and reliability. In order to justify the relevance of the problem, it fulfilled the analysis of the cement mixtures composition for the repair of the construction structures and their demolishing processes against a background of factors under the different operating conditions. It considered the ways to manage the particularities of the repair mixtures using the shrink-resistant and expansible gypsum-alumina-based cement. It reflected the pros and cons of the various types of the repair mixtures and addressed the factors causing difficulty in expanding shrinkage deformation management under the different operating conditions as well as a longevity reduction for the renovated building structures.
