The invention is particularly, but not exclusively, applicable to arch-shaped concrete tunnel lining segments. In the molding of concrete tunnel lining segments, it is common to obtain one or more molded parts from one mold each working day. In some cases, in principle, when using steel molds (and also in the case of concrete molds), the fabricator can create a single molded part by using a steam chamber to assist in the solidification of the molded concrete. can be obtained every 4 to 5 hours. Place the mold in the chamber or
Or cover the chamber with the mold. The chamber is then filled with steam to give the concrete sufficient strength to remove it from the mold within the required time.

い。The present invention is a mold for forming concrete or other cementitious components, comprising a mold surface and heating said surface to accelerate the hardening of the component in the mold. and an electric heating device embedded adjacent to the surface to heat the surface. By incorporating electric heating elements into the mold, the temperature of the wet concrete is increased, causing the concrete to harden more quickly, thereby allowing the molded concrete components to be removed from the mold in a similar amount of time as using steam. is possible. Advantages over using steam are that the energy consumption is relatively cheap and that the mold remains stationary so no extra effort is required. Working conditions are maintained relatively clean since there is no risk of steam condensing and affecting the work area. The cost of wiring and associated control equipment is considerably less than the cost of steam plants and steam chambers.
