Dampen the gravel base before you start, to cool it down, and use cool water to mix the concrete. This will prevent the new concrete from curing too quickly. By slowing down the curing process you’ll reduce the chances of shrinkage or cracking and ensure a better result.
How to Slow Down Concrete Setting?
Concrete has been used for centuries for its durability, strength, and affordability. However, it can sometimes be difficult to work with due to its quick setting time.
If you need to slow down the setting time of concrete, there are several techniques you can use. The first and most important technique is to use a retarder.
A retarder is a chemical additive that can be mixed in with the concrete before it is poured. The retarder will slow down the setting time of the concrete, allowing you to work with it for a longer period of time.
It is important to note that different brands of concrete will require different amounts of retarder, so it is important to read the directions carefully before adding it to the mix.
Another technique to slow down the setting time of concrete is to add more water to the mix. The more water you add, the longer it will take for the concrete to set.
However, it is important to note that adding too much water can lead to a weaker concrete, so it is important to find the right balance.
Also, keep in mind that the ambient temperature can also affect the setting time of the concrete, so if it is particularly hot outside, you may need to add a bit more water than usual.
