Soft to rigid construction materials

[eextreme]

I often enjoyed how when you shape an object with clay and blast it with a furnace, you would be able to turn the soft material into one where you can store water and heavy objects inside, and be resistant to some external forces as well.

Thus, it make me wonder if there are materials that starts out as soft as clay and with very little energy become as hard steel. I visualize something that after you shape it with your bare hands, or clay working materials and then zap that area with some electricity, it becomes strong enough to support a lot of weight.

I would like to know if there is such material and the viability of the material in the construction of new buildings and related architectures.

I look forward to you responses
