Abstract

Procedimiento y su correspondiente instalación para calentar hormigón durante el fraguado en un molde con miras a acelerar su endurecimiento, comprendiendo el mencionado hormigón en su masa por lo menos un armazón que atraviesa el molde en su longitud, consistiendo el mencionado procedimiento en calentar el hormigón por efecto Julio haciendo circular una corriente eléctrica por su masa caracterizándose el mencionado procedimiento porque consiste en: - aislar eléctricamente cualquier elemento distinto del hormigón por lo menos una armazón entre el conjunto de las que atraviesan el molde en su extensión, - establecer directamente una diferencia de potencial entre cada armazón aislada y un elemento metálico conductor en contacto con el hormigón con el fin de hacer circular una corriente eléctrica entre este elemento y esta armazón aislada a través del hormigón húmedo, - mantener la diferencia de potencial por el tiempo que sea necesario hasta que el hormigón así calentado haya alcanzado una resistencia suficiente para el desmoldeado.
