The Effect of Temperature on Concrete Strength

Effect of Weather on Concrete StrengthThe Effect of Temperature on Concrete Strength

Temperature control makes a tremendous difference in early concrete strength performance. In cold weather, concrete temperatures should be controlled with powerblanket™ concrete curing blankets to ensure proper compression strengths are reached as soon as possible. The sooner the concrete reaches the proper strength, the sooner the construction process can continue.

Here’s a breakdown of strength gains after three days at various temperatures:

Temperature – Compressive Strength (psi)

70°F – 2,700

60°F – 2,150

50°F – 1,600

40°F – 1,200

30°F – 850

20°F – 400

To ensure optimal concrete strength, here are some tips for cold weather placements:

  • Use a heated or warm concrete mix.
  • Don’t allow the concrete to freeze – use powerblanket™ concrete curing blankets to control temperature.
  • Don’t place concrete on a frozen sub-grade – use powerblanket™ concrete curing blankets to control temperature.
  • Protect concrete from excessive drying.
  • Incorporate accelerators to maintain strength and normal set time.
  • Avoid rapid changes in concrete temperature with powerblanket™ concrete curing blankets.
