The article provides a comparative analysis of cement markets in Uzbekistan and Kyrgyzstan for 2018-2023. The data on production, foreign trade operations and cement consumption in these countries are given.
The article summarizes the main indicators of the cement industry in the Republic of Korea. In 2022, the country produced 51.1 Mt of cement, 1.2% more than in 2021. The annual per capita consumption of this material remained very high and fairly stable at an average...
The legislation of the Russian Federation for the last few years has been pursuing the goal of the Federal Law No. 89-FZ dated June 24, 1998 “On production and consumption wastes”, i.e. involvement of wastes into economic circulation. One of the first areas in the cemen...
In the face of escalating concerns regarding climate change and environmental impact, the cement industry is actively exploring and implementing the use of alternative fuels to revolutionise its production processes. This article provides a comprehensive overview of the...
The strategy of substituting clinker by supplementary cementitious materials, SCM appears to be the shortest and less capital-intensive path to sustainability. Introducing calcined clays as SCMs in the Russian cement industry will facilitate the production of cements th...
The purpose of the study is to develop cement fine-grained concrete modified with active mineral additives for 3D concrete printing (3DCP) with optimal rheotechnological properties of raw mixtures and physical and technical characteristics of hardened composites...
The mixture of high- and low-calcium types of fly ash and activator, sodium carbonate, can serve as a low-grade clinker-free binder gaged with water. In the alkaline environment created as a result of interaction of binder components and water, the hydraulic and pozzola...
The article examines the effect of thermally activated clays on the properties of Portland cement. It is shown that thermally activated clays can replace up to 25 % of Portland cement clinker without loss of strength and cement quality, which will reduce carbon diox...
The article considers the possibility of obtaining composite cement for hydraulic engineering using finely dispersed aluminosilicate rocks - perlites, a colloidal additive in the form of silica sol and a superplasticizer to increase the crack resistance of hydraulic con...
