Aims

The rehabilitation of reinforced structures is during last 10 years an up-to-date, dynamically developing trend in building industry. The subject-leaver obtains actual information about the whole rehabilitation process,design of rehabilitation and its execution (technology, materials etc.) Obtains the informatin about repair mortars and concrete. Elaboration of practical Individual project includes detailed technological design of specific repair works.
