How long does it take for a concrete sidewalk to harden?
A concrete sidewalk typically takes about 24 to 48 hours to harden enough for light foot traffic. However, it can take up to 28 days for the concrete to fully cure and reach its maximum strength. Factors such as temperature, humidity, and the mix used can affect the curing time. It's best to avoid heavy loads on the sidewalk until it has fully cured.
Will cement harden in the cement truck if it is not rotating?
Actually, the rotation is mainly to keep the concrete well mixed and homogeneous during transport, thereby insuring the sand, gravel, water, and cement is well mixed. The concrete itself will set up or harden at approximately the same rate of time, regardless, whether it is rotating or not. Typical concrete mixes show noticeable hardening/stiffening after approx 2 hours, depending on temperature and other factors.**Note: The correct term is concrete. Cement is actually the dry gray powder, that when hydrated with water, bonds the rock and sand together to make concrete.
What is the setting time of concrete?
The length of time that concrete takes to set, will depend on the temperature. It would take approximately 4 hours for concrete to set at a temperature of 80 degrees.
What is needed to make concrete?
To make concrete, you need three primary ingredients: cement, water, and aggregates (which include sand and gravel or crushed stone). The cement acts as a binder that holds the aggregates together when mixed with water. The water activates the cement's chemical reactions, allowing it to harden and gain strength. Proper mixing and curing are also essential to ensure the concrete achieves its desired properties.
Does the amount of water in a gravel based concrete depends on how fast it will harden?
yes, because after casting, concrete will get its 90% strength within 28 days and proper hydration require the proper amount of water for atleast 28 days.
At what temperature does clay need to be heated in order to harden?
Clay needs to be heated to a temperature of around 1,000 to 1,300 degrees Fahrenheit in order to harden.
What temperature will bread harden at?
it will harden in a hot temperature
How do you cut up a bag of harden concrete mix?
With a sledgehammer.

How can I use concrete for casting sculptures?
To use concrete for casting sculptures, you will need to create a mold of the desired sculpture, mix concrete with water to form a workable consistency, pour the concrete into the mold, and allow it to cure and harden. Once the concrete has set, you can remove the mold to reveal the finished sculpture.
Can you eat concrete?
if you smother it in kethcup you can eat anything Actually no you cannot eat concrete. Well you should not eat concrete, the body is primarily made up of water. What is needed for concrete to harden? Water. Think about it, it would harden in your lower intestine and you would have some hard crap. Literally. Not a good idea.
Are concrete bricks fired?
No, concrete bricks are not fired. Unlike clay bricks, which are baked in a kiln to harden, concrete bricks are made from a mixture of cement, water, and aggregates, and they harden through a curing process. This process involves allowing the concrete to set and gain strength over time, usually in a controlled environment.
What causes concrete to harden?
Chemical reaction of lime and dehydrated gypsum with water.
What are the constituents of concrete?
Concrete is composed of water, cement and sand. It has three constituents. Concrete is mixed as a wet mixture, poured into place and allowed to harden and dry.

What makes melted Candy harden?
A reduction in temperature.
Does Vaseline harden overtime?
No, Vaseline does not harden over time. It is a semisolid mixture of hydrocarbons that remains stable at room temperature.
