📄 Abstract（原文）
The production of a high-quality, competitive Portland cement is one of the urgent tasks, which are necessary for the reconstruction of Ukraine in context of the deconstruction and damage of a large number of infrastructure objects. The technology of cement production is multi-stage and energy-intensive. One of the earliest and most important stages is the decarbonization, which is accompanied by the release of CO2 and formation of a mixture melt. The aim of work was to improve the decarbonization process, which is the primary stage of clinker minerals formation during sintering of the bath. We have investigated on PJSC Ivano-Frankivskcement an effect of the additive NaF (1-5%) on the raw material: limestone, marl and pyrite cinders in comparison with the model reaction. It has been proven, that sodium fluoride accelerates sintering of limestone and marl, but in the case of pyrite cinder, on the contrary, it slows down. The action of mineralizator comes down to lowering the temperature, appearance of the melt in the mixture that accelerates speed of sintering and contains crystalline quartz and limestone. Under these conditions, favorable conditions are formed for dissolution of CaO and C2S. The use of the mineralizator is recommended by calcination of raw mixtures. It has been established that NaF additive in the amount of 2% by the mass accelerates the process of interaction between CaO and SiO2, promotes the formation of aluminate and ferrite phases at lower temperatures. X-Ray analysis was conducted, proving that the use of mineralizer is expedient during raw mixture sintering. This work is important for improving Portland cement production technology by reducing the temperature of the decarbonization process through the introduction of the NaF additive.
