Monolithic construction has problems in field of providing with needful temperature conditions of hardening and development of strength concrete in winter. One of technologies of winter concreting is electric curing with using heating conductor. Technology of heating concrete by wire during winter concreting of thin-walled constructions was explored in article. Authors give guidance for selections of heating conductors, materials and mechanisms, wiring plan with the aim of improvement and optimisation in concreting technology. Analysis of risks in technology of winter concreting with using heating conductor was made. Modeling of emergency of open conductors on area of monolithic floor was produced.
