Use of Waste From Aluminothermic Welding of Railroad Tracks in Structural Materials Science

The article discusses the possibility of using mineral waste from the aluminothermical rail welding in the form of waste refractory forms, and slag in construction materials in the preparation of ceramic, refractory and cement containing materials. The article provides optimal compositions using crushed and ground mineral waste and physic-mechanical studies of the obtained construction materials. For the study of the waste phase composition and structure of synthesized materials powder x-ray diffraction, differential thermal analysis and electron microscopy were used.
