← HistoryWhich material property limited widespread construction of large-scale Mayan maize storage silos?
A)Inadequate tensile strength of lime plaster✓
B)Poor thermal conductivity of volcanic rock
C)Excessive permeability of woven reed roofing
D)Insufficient compressive strength of adobe bricks
💡 Explanation
When constructing large storage silos, the tensile strength limitations of lime plaster became limiting, because this resulted in cracking and weakened structural integrity under the outward pressure of stored grain. Therefore insufficient tensile strength hinders silo volume, rather than thermal conductivity, permeability or compressive strength which affect different loads.
