Hot weather affects set time, finishing windows, and strength development—especially on large slabs. Here are practical controls for better outcomes.
Texas heat presents real challenges for large slab pours and high-square-footage placements. Rapid moisture loss can cause plastic shrinkage cracking and reduce surface durability if it is not managed.
Concrete typically reaches initial set within 24 to 48 hours, but full curing takes approximately 28 days. During hot Texas summers, rapid moisture loss can cause surface cracking and reduced strength.
Common controls include: placement timing (early hours), curing compounds/wet curing as specified, wind breaks, and mix design coordination. Always follow project specs and engineer requirements.
