Chapter 474
Alexander's ability to build a 4 story building every 3 days was certainly very impressive, as evidenced by the fact the logistics of furnishing the building were unable to keep up with the speed.
And it might even sound like a complete farcical claim to some as such a building would take, even by modern standards six months to complete, though it could be argued that modern buildings needed a lot of internal finishing such as electrical wiring, plumbing, and HVAC (heating, ventilation, and air conditioning), all of which could be skipped with Alexander's apartment.
But even then, one needed to simply give the concrete roof on each floor at least a month to dry and cure, where first the water on the surface would evaporate, leaving the dry cement.
Following this, the material would undergo a process called hydration and several chemical reactions would occur inside it to reach its optimal strength.
