Planned learning activities and teaching methods

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations. The course consists of lectures and laboratory sessions. Information is presented to students in the form of lectures. In laboratory exercises, students work in groups and carry out the assigned tasks according to exercises plan. The output of each exercise is protocol with the evaluation of the measured values.

Assesment methods and criteria linked to learning outcomes

Credit – attendance at exercises, preparation and submission of reports from exercises in the required scope, form, quality and time, test (pass mark at least 60 %).
The final exam consists of a written and oral part.

Course curriculum

1. Mechanism of hemihydrate gypsum formation, depending on the manufacturing process: beta gypsum, alpha gypsum during the hydrothermal treatment, alpha gypsum from a solution of salt.
2. Improving the properties of hemihydrate gypsum: hydrophobic, set retarding and plasticizing additives, overview and mechanism of action, influence of milling of gypsum.
3. Improving the properties of anhydrite: activator additives, antifoaming agents, pigments, influence of milling of anhydrite.
4. The use of limestone for desulfuration energy and chemical industry.
5. Other uses of lime and limestone in engineering practice outside the building.
6. Preparation of hydraulic lime: hydraulic lime mortars for historic and plaster, hydraulic lime with pozzolanic component based waste materials.
7. The use of waste materials as part of the raw material base for clinker firing and preparation of composite cements: recycling waste from building industry, fluid fly ash, industrial gypsum etc.
8. Belite cement: belite cement special features, possibilities to improve the kinetics of the hydration process.
9. Other special cements.
10. Structure and mechanism of formation of clinker minerals and their hydration fumes.
11. The basic raw material for the production of dry mortar mixtures: binders, fillers, additives, alternative raw materials.
12. Preparation and properties of dry mortar mixtures: mastics, plasters, mortars.
13. Preparation and properties of special dry mortar mixes: leveling mixed with a binder based on anhydrite, aluminous cement and portland cement, shielding barytic mixtures.
