- Аннотация: The authors propose plasma practice of clinker obtaining. This study presents good results of studies of clinker obtaining by plasma practice. Using different raw materials Portland cement clinkers were obtained having various modulus and lime saturation factor. The results of SEM, optical microscopy, XRD and other techniques showed the peculiarities of melted clinkers, obtained by plasma method, in comparison with sintered clinkers. The results showed that it is possible to obtain cements on the basis of melted clinkers, having compressive strength equal to 50-80 MPa and higher. The bending strength was 5-8 MPa after 28 days of hardening. The cements therewith can be classified as fast-hardening ones. Thus it is possible to obtain clinkers using unconditional raw materials and industrial waste for production of fast-hardening, high strength, sulphure resistant, high alumina cements and other types of cements.
