“When I examined this area, I found that the stone at the east side was placed there in 1939 to support this area as restoration, and was supported by cement...This is why this area had a higher temperature than other blocks,” said Hawass."

78 years - probably cured by now however concrete's ability to absorb and retain heat is different from limestone.

""Digging deeper into the curing process, hydration is the chemical process that allows concrete to go from a plastic state to a hardened state while gaining strength over time. Hydration occurs at a faster rate in the early stages after concrete placement and slows down after a month or so goes by. Many cement pastes will cease hydration before one year, and some may continue to hydrate over the course of several years (4). Because of the variable length of the hydration process, the phrase “green concrete” is a purely subjective characterization.""
