USE OF ELECTRICITY TO ACCELERATE THE HARDENING OF CONCRETE

L'ACCELERATION PAR L'ELECTRICITE DU DURCISSEMENT DES BETONS

The electric heating of concrete is a recent process, the first commercial application of which goes back approximately fifteen years. This technique completes the range of conventional methods of accelerating the setting and hardening of concrete such as addition of special binders, the use of chemical admixtures, heating with steam, warm air or hot water. The electric hardening of concrete offers many advantages, especially for large sites and the manufacture of precast concrete. Details are given of different electrical techniques: by means of the reinforcement heating with wires immersed in the concrete, heating through the concrete mass, electrifying of the formwork, heating of the working area, electrically heated cover, infrared heating and electric ovens. /TRRL/
