Computer Simulation of Electric Curing of In-Situ Reinforced Concrete Structures

Abstract

The paper presents the results of computer simulation of electric curing of in-situ reinforced concrete columns using the ELCUT Pro 6. 3 software. The purpose of this work is to solve the thermodynamic problem of electric curing under freezing temperatures. A block of a monolithic residence building under construction (Tomsk, Russia) is assumed as a basis. The importance of this research arises from the need to provide the temperature conditions for concrete curing and strength gain in winter. The initial parameters are introduced in the ELCUT Pro with the WinConcret add-in for the built structures. As a result, the rod electrode spacing is determined to provide a uniform distribution of temperature fields over the structure cross-section. The time of isothermal concrete heating and the concrete strength are identified depending on the outside temperature. Rationale is prepared for the mold heat insulation for in-situ reinforced concrete columns, depending on the outside temperature. Based on the ELCUT Pro simulation, the electric curing technique is proposed for reinforced concrete columns at freezing temperatures. This technique is deployed in on-site conditions.
