Only in this case can we say that all the rules for the manufacture of a concrete solution were observed.
If the work is performed for the winter period, then it is advisable to insulate the formwork, and after the end of concreting, warm the upper surface of the concrete with shields and mats. If you follow all the rules, then the concrete mixture is laid in the formwork either from wooden or from metal shields, which must correspond to the shape of the future structure. The ranger is built into the formwork, which plays the role of the frame. Put the solution in the formwork as quickly as possible and without breaks.
