The drying time of ready-mix concrete can vary depending on several factors, such as the mix design, environmental conditions, and project specifications. Generally, ready-mix concrete will start to set and harden within 1 to 2 hours after pouring. However, it’s important to note that the concrete will continue to gain strength and cure over time.

The workability of concrete refers to the amount of time it remains in a plastic and moldable state after mixing, allowing it to be easily placed, compacted, and finished. The workability of concrete can vary depending on several factors, including the mix design, ambient temperature, humidity, and the use of admixtures.

In general, the workability of concrete typically ranges from 1 to 2 hours after the initial mixing. During this time, the concrete is in a plastic state and can be easily shaped and manipulated. After this initial period, the concrete starts to set and harden, becoming less workable.

The best concrete mix for a slab will depend on the specific requirements of the project and the intended use of the slab. However, a commonly used and recommended concrete mix for a standard slab is a 1:2:3 mix.

The 1:2:3 mix refers to the ratio of cement, sand, and coarse aggregates by volume, respectively. This means for every part of cement (1), you will use two parts of sand (2) and three parts of coarse aggregates (3).

Concrete does not fully dry in just 3 hours. After being poured and placed, concrete undergoes a process known as hydration, where the cement particles react with water to form a strong, solid matrix. This process takes time and continues for an extended period.

In the first few hours after pouring, concrete goes through the initial setting stage, during which it begins to harden and gain some initial strength. However, even after 3 hours, the concrete will still be in a plastic and moldable state.

It’s important to note that concrete requires sufficient time to achieve its desired strength and durability. While it may be possible to walk on or apply light loads to concrete after a few hours, it is not fully cured or ready for heavy use. For structural applications and maximum strength, concrete should be allowed to cure for at least 7 days.

If you don’t water concrete during the curing process, it can have several negative consequences on the strength, durability, and appearance of the finished product. Proper and adequate curing is essential to ensure the long-term performance and integrity of the concrete.
