• use of FRP materials in concrete structures;
• experimental and numerical analysis of reinforced concrete and prestressed concrete structures under fire conditions,
• multi-field issues in the analysis of concrete structures, modelling of environmental interactions (alkali-aggregate reaction in concrete);
• numerical modelling of load-bearing capacity and deformability of concrete structures, analysis of the scale effect;
• verification of the performance of reinforcing bars in terms of adhesion of steel to concrete by means of a pull-out test;
• non-destructive and semi-destructive methods of identifying the mechanical properties of masonry elements in existing buildings;
• models and analyses of historic masonry structures and methods of their strengthening;
• analysis of changes in the temperature of hardening concrete in semi-massive and massive reinforced concrete structures;
• analysis of the crack risk and maturing concrete cracking;
• analysis of imposed strains, residual and imposed stresses in semi-massive and massive reinforced concrete structures;
• theoretical models of corrosion progress in structural members, together with their verification;
• models of work of the anchorage zone of prestressing tendons and their calibration;

Characteristics of the main directions of scientific and research work:

Scientific and research work carried out by the Chair as part of its research, statutory activity, grants and research work for the industry covers a wide spectrum of issues related to the broadly understood civil engineering industry. First of all, these are issues in the field of structural materials and products, especially in the field of concrete and other cement materials. Besides, the team’s competencies also include technological issues, designing properties and durability of materials and its conditions. The subject of technology, properties and broadly understood durability of mineral materials are particularly developed, including mainly such materials as concrete and cement mortars, geopolymer concretes and mortars, soil- cement, structural ceramics.

The research topics undertaken by the Chair’s employees in recent years include extensive research on the possibility of utilization of sewage sludge, which, after thermal processing, is a valuable addition to cement concretes.

In the field of cement composites, tests are carried out on: ordinary concretes and new generation concretes (high-performance and ultra-high-performance, self-compacting, lightweight aggregate concrete, fibre-reinforced concrete, self-healing concretes). These tests concern both technological aspects (composition design, evaluation of technical properties, etc.) and durability in various operating conditions – from cyclic freezing and thawing to high-temperature impact studies. Also, the team is investigating the effects of corrosion of mineral materials caused by biological agents.

The team conducts numerous research works on geopolymer composites. The problems related to the influence of their composition (selection and evaluation of the impact of the use of various aggregates, precursors and alkaline activators) on the properties of the mixture as well as the usable properties and durability of the hardened material are analyzed. Work is ongoing to use the special resistance of these binders to high temperature and to determine their resistance to chloride.

When characterizing the research activity of the Chair’s team, it should be emphasized that in all research conducted at the Chair, great emphasis is placed on the aspects of sustainable civil engineering.

The Chair’s scientific and research activity is financed both from internal funds and, to an increasing extent, from external funds as a result of European and national competitions (ERA-NET, NCN, NAWA, NCBiR, etc.). Scientific and research work is carried out in international cooperation with scientific research centres and universities. Scientific and research activities constitute a strong basis for extensive didactic activity, primarily in the field of subjects important in the education of a civil engineer, related to the broadly understood structural materials science.
