Abstract:
1. A recyclable formwork for use at an outdoor working site, comprising: a main unit having a contact surface for contact with cast concrete, a non-contact surface that is parallel and opposite to the contact surface, and a plurality of ribs projecting from the non-contact surface in a direction away from the non-contact surface and reinforcing said main unit; a case housed between the plurality of ribs and fixed on said main unit on a non-contact surface side of said main unit; a circuit in said case; a separator extending through a hole in said main unit so as to directly contact the cast concrete and remain within the cast concrete after the cast concrete has hardened; a temperature sensor on said main unit so that said temperature sensor is in thermal contact with said separator so as to be in thermal contact with the concrete cast on the contact surface and so as to measure changes of temperature of the concrete cast on the contact surface and send temperature signals to said circuit in said case, and so that said temperature sensor does not directly contact the cast concrete.
