Pre-Pour Steps to Speed Up the Drying Process Web“Curing of concrete can be defined as assuring the concrete in a moist and warm condition enough so that the hydration of cement can continue. More precisely, it can be defined as the process of maintaining satisfactory moisture content and a favorable temperature in concrete during the period immediately following placement.
WebAfter 7 days, the concrete will have gained around three quarters of its compressive strength, but you should refrain from driving vehicles or heavy machinery over the surface until after the 28 day mark. For domestic mixes – driveways, for example – you can expect the concrete to be set within 24-48 hours. WebIn fact, in hot and sunny climates, the surface temperature of dark-colored concrete can reach up to 20-30°C (36-54°F) hotter than the surrounding air temperature.
