What temperature does concrete need to be to harden?
all things that need to dry are based on 72 degrees concrete needs 30 days to fully cure.
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.
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.
How long does it take for concrete to harden?
it takes 28 days to fully cure, It would be advisable not to drive on it before that because of micro cracks, which will continue to migrate through time, causing spiderwebbing outside of your control joints, Depends on the cement used some quick cure cements can harden in an hour
What is a grey powder that is mixed with sand and gravel to make concrete called?
The grey powder mixed with sand and gravel to make concrete is called cement. Specifically, it is often Portland cement, which is the most common type used in construction. When combined with water, cement undergoes a chemical reaction that allows it to harden and bind the aggregates together, forming solid concrete.
How do you cut up a bag of harden concrete mix?
With a sledgehammer.
Can you eat concrete?

What temperature does concrete need to be to harden?
all things that need to dry are based on 72 degrees concrete needs 30 days to fully cure.
Can you dry pour concrete without adding water?
No, you cannot dry pour concrete without adding water. Water is necessary to activate the chemical reaction that causes the concrete to harden and set properly.
Why does concrete have to be placed compacted and finished within a certain time from when the concrete was mixed?
Concrete cures and hardens from chemical reactions over a specific period of time. If the concrete work is not completed within the specific period of time, the fluid concrete will harden and become unworkable.
What is meant by binder material in concrete?
The binder in concrete is usually cement. Cement causes the aggregate and sand to bind together mechanically and harden to make a solid surface.
What material is very durable artificial rock?
No. Cement is used to hold the rocks of concrete together. Cement by itself does harden in water. but it not a very hard or durable product.
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.
How to make concrete from scratch?
To make concrete from scratch, mix cement, sand, and gravel in specific proportions with water. The mixture should be thoroughly combined and poured into molds to set and harden.
Is concrete natural?
Concrete is not considered natural as it is a man-made material produced by mixing cement, water, and aggregates like sand and gravel. It undergoes a chemical reaction, called hydration, that causes it to harden and set.
