Abstract
Introduction. The article discusses the types of channeling agents, their application and advantages, as well as ways to improve and technology of application. The differences between channeling agents working together with concrete, the advantages of channeling agents extracted from concrete compared to non-recoverable ones, reusable and single-use channeling agents, as well as their structures made of combustible materials and made of shape-memory metals and screw channeling agents are shown.
Aim. The study of the most promising, in our opinion, channelizers.
Materials and methods. A patent search was conducted for the latest proposals on this topic, initial studies and comparative analyses of the application of the proposed channelizers were conducted.
Results. The results obtained made it possible to recommend new technologies for the use of channeling agents.
Conclusions. Work on the application of new technologies for the use of channel formers should be continued in more equipped laboratories and that technologies should be recommended for use.
