How long does concrete need to cure?

Concrete should be cured for at least 24 to 48 hours before formwork is removed and the surface can be walked on. After 7 days*, the concrete is partially cured and strong enough for equipment and vehicles. After 28 days, concrete should be fully cured.

Poor curing can reduce concrete strength by up to 50%, and increase the risk of shrinkage-induced cracking, despite control joints being saw-cut. Cracking typically becomes noticeable after two weeks at the earliest and cracks can continue to widen for months. The risk of shrinkage cracking is minimised by using reinforcing, the correct positioning of control joints, compaction and using the appropriate concrete mix.

Effective curing also improves concrete durability and abrasion resistance.

How much does weather affect laying or curing concrete?

Temperature: The ideal temperature for curing concrete is about 20°C. Concrete-iT doesn’t lay/pour concrete at the hottest time of day, or when it is too cold (e.g. under 5 °C, as the concrete may freeze, then not cure properly).

Rain: It’s best to avoid placing (laying/pouring) concrete if it may rain. If the concrete has been floated,  trowelled, and is nearing setting before it rains, the damage may be limited to marking on the surface.

How long does concrete last (and compared to asphalt)?

The life expectancy of concrete depends on factors such as: the quality of the installation, environmental conditions, and whether or not the concrete is kept well-maintained and not subjected to excessive loads. Concrete can last for up to 50 years (especially if it is sealed), asphalt up to 30 years.

Laid correctly, concrete can hold a higher load than asphalt, and asphalt is not as durable in high temperatures.

Should concrete be sealed?

Sealing extends the life of concrete and any decorative finishes used (especially coloured/stained/etched concrete). It’s cheaper and easier to apply a sealer every few years, then it is to repair cracked concrete. For driveways, Concrete-iT recommends sealing approx. every three years.

Sealing concrete protects it against wear and tear/abrasion, marks and stains. It also helps help prevent the growth of moss, mould and lichen. Sealing concrete also adds to the aesthetic appeal, which can add value to a property. Note: It’s important to use the right sealer, gloss level and slip-resistance – e.g. based on the concrete texture.
