Abstract <p>At the present stage of development of the construction industry, one of the most important tasks is to ensure the durability of structures, which can be achieved by protecting building structures from the corrosive effects of the environment. The growth of construction production requires a constant increase in output, development and application of new effective building materials with high physical and mechanical properties, improved performance indicators and durability. The search for ways to improve the quality of cements and increase the output of cements during the creation and implementation of low-waste and waste-free technologies continues on a large scale. The most promising solution for creating corrosion-resistant concrete that ensures the durability of building structures is the use of effective composite binders in their compositions. In Russia and other countries, sulfate-resistant cements are produced, which are used in the construction of facilities exposed to the corrosive effects of mineralized waters. However, their production volumes are limited by the raw material base. In the Republic of the Union of Myanmar, sulfate-resistant cements are not produced and these materials have to be imported for the construction of offshore structures. In this regard, the development of compositions of composite cements based on Portland cement clinkers of non-standard composition, with increased corrosion resistance, is very relevant. In this article, construction and technical properties of cements based on sulfaolumoferritic clinker with the addition of gypsum during hardening in water and in aggressive solution Na₂SO₄ are shown in details. It has been established that sulfoaluminoferrite clinker (SAFC)-based cements with additives of two-water gypsum make it possible to obtain corrosion-resistant cements with good strength characteristics both when hardening in water and in an aggressive environment—5% Na₂SO₄ solution.</p>
