Course objectives
Technology of silicates is usually understood as the problems connected with Portland clinker manufacturing technology and phase equilibriums, which are used for explanation of studied phenomena. The course is oriented mainly to the chemistry, mineralogy and microstructure of mortars and building materials.
Syllabus
  • 1) Introduction to chemistry and technology of cement. Binding agents, mortars, cement. Non-hydraulic, blended with hydraulic admixtures, latently hydraulic and hydraulic mortars 2) Overview of most important raw materials and their required properties 3) Primary and secondary raw materials for clinker manufacture: clay, carbonate and corrective raw materials. 4) Mechanism and kinetics of clinker creation. Three basic kinetic stages. Influence of the content of fluid phase and effect of secondary components to the speed of silicate clinker creation. 5) Technological systems: wet, semi-dry, dry. 6) Aerial and hydraulic binding agents. Romanesque cement, Portland cement, classification of cements according to the sort and classes in correspondence with the new CEN standards (European Committee of Standardization seating in Brussels) 7) Manufacture of Portland cement - the essential clinker minerals. Structural and microstructural characteristics. 8) Chemical and phase composition of silicate clinker. Methods of study. 9) Stability and petrografical characteristics of different degrees of fires, influence of cooling mechanisms and stability of phases. Dark and light interstitial substance. 10) Microscopic methods of study. Identification of clinker minerals in passed through and reflected polarized light. Methods of etching, etching agents and their effect. 11) Reaction of cement with water. Principles of hydratation and mechanism of clinker phases hydratation. Microstructure of cement paste. 12) Most frequently used types of cement.
