Course abstract

In lectures: In the study course, students expand and strengthen their knowledge of new and modern construction products to essential and specific technical properties. The theoretical course is briefly discussed in the lectures. To acquire general topics, students are focused on study literature.
In the laboratory works: students get acquainted with some modern methods of testing building materials and before the laboratory works the students develop the summaries of the corresponding topic - theoretically get acquainted with the testing algorithm of the specific building material (testing methodology). During the work of the laboratory practically develops and observes (documents - records, photo fixation) the experiment - test process, analyzes the obtained results, provides written conclusions. Laboratory works and their summaries are developed, defended and filed in a common folder.
Practical works:
• students listen to the theoretical introduction and observe a practical demonstration of the corresponding process, perform documentation, develop a protocol (observation, analysis, conclusions). Protocols of practical work are developed, defended and placed in a common folder with laboratory work.

Learning outcomes and their assessment

Knowledge: upon completion of the study course, students must know the most important technical properties of modern construction materials and construction products, their testing methods and application possibilities, be able to choose construction materials for specific construction works, know the basic rules of construction product circulation, as well as be competent to analyze construction product testing reports and purpose of use. Knowledge assessment: tests are written. Exam: written - verbal.
Skills: skills to choose the technological method for obtaining materials, guided by the required specific properties and application. Ability to choose the best material for a specific application to obtain the required result (skills assessment: defended laboratory and practical work reports - protocols - summaries).
Competence: is able to evaluate and rationally justify the choice of construction materials, apply construction norms and appropriate standards, use professional terminology (competence assessment: verbal defence of laboratory and practical work; exam).

NOTE: the student independently prepares handwritten conspectuses on the listed topics of laboratory work before the laboratory work, that is, arrives at a laboratory work lesson with a theoretical knowledge base on the task to be performed in the laboratory work. Conspectuses should be made on an A4 format sheet, which is then placed in a common folder (the student can prepare copies of the abstract, which will be handed over to the lecturer).

Criteria for Evaluating Learning Outcomes

Practical and laboratory works are assessed by the lecturers in accordance with the assessment procedure and defined requirements (some pointers: calculated results and units of measurement must be presented; clearly, comprehensibly and legibly written; stripes (corrections) must be covered with a white proof-reader; ballpoint pen used as a pen, laboratory and practical work protocols must be signed). All works are designed in accordance with the Faculty of Environment and Civil Engineering student work methodological instructions. Additional criteria for the assessment of study results: attitude, adequacy and correctness of information; demonstration of knowledge, skills and competence in defending laboratory work.
