the possibility of creating uniformity of the layer;
compliance with the condition of the without no effort of the constructed design.
For the possibility of creating interruptions in concreting, additives are introduced into the mixture, which slow down hardening. In the winter, on the contrary, to accelerate solidification, other additives and “warm” concreting can be used: use systems with electrical and infrared heating. To facilitate the process of leveling and sealing, plasticizing additives are used.
