Historically the longest lasting building materials seem to be stone. But I was wondering what material modern technology can create that would last longer under various conditions.
The various things the material would need to be tolerant to would include extreme heat, cold, water, wind, plants, animals, sunlight, earthquakes, as well as a determined effort by people to deface, damage or destroy.
I had considered steel blocks with a coating of an alloy or metal that would not react to air or water, or maybe an advanced form of composite glass or plastic such as bullet and bomb resistant glass that would be multiple feet thick and reinforced with metal as well.
I was planning to ask this question in an architecture stack, but all I could find was home improvement and I thought engineering may have more people versed about materials science than do it yourselfers.
So, if a modern team was going to build a pyramid and wanted it to last much longer than those of Egypt what materials would likely be used?
