APPLICATION OF WATER JET TECHNOLOGY FOR CONCRETE REPAIR

Abstract

This article brings selected knowledge from the long-term cooperation between the Brno University of Technology, the Faculty of Civil Engineering, the Institute of Technology of Building Materials and Components, and the Academy of Sciences of the Czech Republic, v.v.i., Institute of Geonics, Ostrava – Poruba in the field of the interaction of water jets and concrete, especially with regard to the use of water jet technology for the removal of surface layers of concrete during repair of concrete. Attention is paid to monitoring the quality of the concrete surface treated by water jet technology and creating a relief in concrete to achieve good cohesion of concrete with repair mortar. The absence of cracks in the concrete structure after water jet blasting has been proven.
