The course is focused on building materials and environmental issues of construction. Learning outcomes of the course unit The aim of the course is to acquaint students with the basic types of large-scale industrial wastes that can be used as alternatives of primary raw materials in the production of building materials. Students will acquire knowledge in the field of secondary raw materials arising from the extraction of silicate building raw materials (tailings, thermally altered rocks, waste sands etc.), secondary raw materials from metallurgy (blast furnace and steel slags, foundry sands), secondary raw materials from energetics (high temperature and gypsum) and secondary raw materials from construction and demolition (concrete recycled, recycled aggregate). The chemical and phase composition and physical properties of the basic types of wastes are discussed in detail, ie parameters that clearly determine the possibility of practical use of each of the mentioned secondary raw materials. Emphasis will also be placed on the environmental and construction risks of the use of individual wastes. Students will acquire practical skills in the field of construction testing in the field of properties and composition of these raw materials.
