Abstract: The purpose of this article is to characterize basalt rocks as an alternative raw material for the production of Portland cement clinker and to evaluate its possible use as an additive in the cement industry. It describes the physical, chemical, and microstructural characteristics of basalt clinker, as well as the effect of its addition to Portland cements on the hydration, water demand, setting, and mechanical strength of standardized mortars. Basalt mixtures can be successfully used as an aluminosilicate raw material to partially replace traditional raw materials, resulting in resource savings and ensuring the quality of the cement produced. The study of the use of basalts together with limestone materials can be important from the point of view of cement technology. The basalt mixture reduces the specific weight of cements. The results of tests of cements based on basalt mixtures for compressive strength showed that basalt reacts with the elements present in the media in the long term, and also increases the strength. The study demonstrates the potential of using basalt rocks as a substitute for raw materials in the traditional production of Portland cement. It was shown that the operating conditions of the furnace may have to be adjusted depending on the quartz content in the basalts.
Key words: basalt, limestone, cement industry, Portland cement, raw materials, construction.
