Resum
This paper analyzes, both experimentally and numerically, the effect of thermal curing on the evolution of temperatures, rate of temperature rise and cooling, stresses and strengths in reinforced concrete elements. It also describes the experimental program carried out to characterize thermally and mechanically the high strength concrete used in the precast segments of the Pajares Tunnel lining. The thermo numerical analysis allows verifying whether a given cycle complies with rules of good prac...
