The process of curing concrete is both an art and a science. The best and most thoroughly cured concrete yields maximum strength and durability which can last for decades.
Curing happens as the concrete particles and the available moisture form crystals, which gives the concrete its strength. Normally, concrete reaches 70% strength after 7 days, and up to 100% after 28 days.
Ideally, concrete should be cured in temperatures of 50° to 75° Fahrenheit- anything too low makes the process much longer, while anything higher than 90° will result in weak and improperly cured concrete.
But, what if you are located nearer the equator, or planning to do construction during the summer? Is it still possible to work with concrete?
The answer is YES. Here is how to properly cure concrete on a hot weather:
