Concrete Curing Time and Duration

Concrete Curing Time and Duration – Any time you have 3 consecutive days where the average daily temperature is less than 40°F or if the temperature is lower than 50°F for less than half of any of the 3 days, concrete thinks it’s cold.

What is the curing of Concrete?

Curing is the process in which the concrete is kept moist to protect it from loss of moisture due to atmospheric temperature and hydration reaction.

We can explain same thing as following-



Curing plays a vital role in concrete strength development and durability. After adding water to the concrete mix (Cement, Sand & Aggregate), the exothermic reaction (hydration) takes place which helps in concrete to harden. As hardening of concrete is not instant and continues for a longer period which requires more amount of water for processing hydration. Curing takes place immediately after concrete placing and finishing, and involves maintenance of desired moisture and temperature conditions, both at depth and near the surface, for extended periods of time. To accommodate this, concrete is kept moist till the hydration reaction completes. This process is called curing of concrete. Properly cured concrete has an adequate amount of moisture for continued hydration and development of strength, volume stability, resistance to freezing and thawing, and abrasion and scaling resistance.



As there are many frequently asked questions about the curing of concrete. Here I am discussing all your queries and imported them in a single article “curing of concrete”.

Pouring concrete in cold weather can have a detrimental effect on concrete curing for several reasons. Accelerating strength gain aims to create a favourable temperature for hydration to occur.

Steam curing. This method is useful in cold weather or when early strength gain is important. There are two methods of curing: live (or low pressure) steam at atmospheric pressure, and.

Walking: We suggest you wait at least 24 hours after the concrete has been finished. For stamped and decorative finishes this time frame will likely increase.

Driving: We recommend that you not drive on the new concrete for 7 days. Maximum Compressive Strength. In normal concrete work, the maximum compressive strength that can possibly be obtained is generally reckoned to be about 7,500 psi for a 28-day cylinder.



Curing Time for Concrete. In standard industrial cases, full strength concrete is recognized at 28 days. At seven days, you should have concrete that is cured to 70% full strength or greater. But to answer the question of, “How long does concrete take to set?”, concrete setting time is generally 24 to 48 hours.

We have had plenty of customers who did not want to wait that long and drive on the concrete 3 days after it was placed without having any problems. So it can be done with small cars and light trucks but we recommend 7 days.The full 28 days for heavy equipment or large heavy trucks(ex: a concrete truck).

Curing is a term in polymer chemistry and process engineering that refers to the toughening or hardening of a polymer material by cross-linking of polymer chains brought about by electron beams, heat or chemical additives.

When the additives are activated by ultraviolet radiation, the process is called UV Cure.curing (crops) Definition. Postharvest treatment of crops to reduce water loss and decay during storage.

In root and tuber crops, curing refers to the process of wound healing with the development and suberization of new epidermal tissue called wound periderm.

After final finishing, the concrete surface must be kept continuously wet or sealed to prevent evaporation for a period of at least several days after finishing. See the table for examples. Application of liquid membrane-forming compound with hand sprayer. Slab on grade covered with waterproof paper for curing.
