Cold joints can reduce the overall strength and durability of concrete structures due to weaker bonding at the interface. This discontinuity occurs because the older material has passed its initial setting time, preventing a true chemical bond with the fresh mix. These joints can compromise structural integrity by creating weak points prone to cracking, water infiltration, and reduced load-bearing capacity.
