Which risk increases when a concrete column's pour halts mid-height?

💡 Explanation

Discontinuing concrete placement leads to a cold joint formation because hydration progresses unevenly, therefore weakening the column's structural integrity rather than improving load transfer or material properties achieved through monolithic pours.
