Which construction risk drastically increases when mortar setting accelerates excessively in traditional Inca stone masonry?

💡 Explanation

Accelerated mortar setting shrinks prematurely, thus creating differential stress; because the interlocking stones cannot slide easily, built-in stress rises drastically due to constrained volumetric alteration. This built-in stress leads to cracking or displacement, rather than expansion as it sets, that might otherwise be accounted for.
