On the Increasing Role of Calcium-Magnesium Carbonate Rocks in the Development of Modern Mineral Binders

Abstract

The development of modern mineral binders that meet the requirements of sustainable development requires the expansion and adaptation of the mineral resource base of the cement industry for the production of low-emission varieties of binders with a gradual decrease in their resource and energy intensity. In recent decades, the composition of Portland cements has undergone significant changes, consisting in an increase in the range and content of mineral additives in the composition of composite and multicomposite cements. At the same time, the increase in the raw material diversity of mineral additives is achieved by searching for more common and affordable mineral resources compared to traditional pozzolanic additives and mineral fillers. This article discusses the latest trends in the development of research and standardization, shows the increasing role of clinker and non-clinker mixed binders with calcium-magnesium carbonate rocks.
