Profession characteristics
Doctoral degree programs are primarily aimed at graduate employment in science and research, which is, among other things, anchored in the objectives of study, learning outcomes and graduate profile. This implies the employment of graduates especially in organizations, institutions and companies that are engaged in research and development activities. These are mainly research organizations whose main activity is research and development, but also construction practice entities, ie companies, where research and development is one of the part of the whole spectrum of activities in addition to commonly realized activities such as production and implementation. A number of implementing companies are currently creating support for their own research and development as they can strengthen their position, competitiveness and marketability in a highly competitive environment. In this regard, there is a growing demand for younger generation professionals with independent creative scientific work, knowledge and insight into new modern trends not only in their expertise but also in related expertise and activities such as PC modeling, simulation, experimental methods and procedures. Last but not least, the graduate has the opportunity to work in the academic sphere, which involves combining scientific research and educational activities. Graduates can thus find employment especially in research organizations and construction practice companies in the context of related development and innovation activities, in educational institutions, especially in the university sphere, which provides them with the possibility of further personal and career development and professional academic growth. Moreover, experience shows that graduates of doctoral study programs are very successful in organizations of the mentioned types not only in the Czech Republic but also abroad, which is also true for graduates in the field of Construction and Transport Structures. Completion of the doctoral study program gives graduates very good prerequisites for employment in, for example, design organizations or state administration in higher professional and managerial positions.

The use of recycled aggregates for the production of concrete is relatively complicated. Recycled aggregates, which are made from construction and demolition waste, do not reach the qualities of natural aggregates.

One way to improve the properties of recycled aggregate is by surface treatment.
