Research of the features of the formation of the structure and properties of building composites based on clinker-free binders of alkaline activation with the use of unconditional natural and secondary raw materials

Abstract

The anthropogenic load on the natural resource potential of the planet is growing rapidly. Therefore, special attention is paid to the development of less costly and low energy-consuming technologies for obtaining new building materials. Those materials do not require high-temperature and expensive technological processing, and this will allow the use of local secondary and substandard raw materials. The development of formulations for linker-free binders of alkaline activation based on fine powders of aluminosilicate nature will make it possible to obtain new effective building composites. The work reveals issues related to the theoretical foundations of the structure formation and strength of cement stone based on an alkaline activator. The research results, in our opinion, have a practical importance for the construction industry, since the proposed formulations of clinker-free cements can replace expensive and energy-intensive Portland cement, allowing creating strong and durable concrete and reinforced concrete structures. The results presented in this article were obtained in the framework of research on the implementation of scientific project No. 05. 607.21.0320. “Development of technology for new building composites based on linker-free binders of alkaline activation using substandard natural and secondary raw materials” supported by the Federal Target Program “Research and Development in Priority Areas of Development of the Scientific and Technological Complex of Russia for 2014-2020” The unique identifier for the agreement is RFMTFI60719X0320.
