Chemical reaction of lime and dehydrated gypsum with water.
The binder in concrete is usually cement. Cement causes the aggregate and sand to bind together mechanically and harden to make a solid surface.
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.
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.
With a sledgehammer.
Concrete is not a compound after water evaporates and it hardens. Concrete is a mixture of aggregate materials (such as sand and gravel) and cement, which binds the materials together. When water is added to the mixture, a chemical reaction occurs with the cement that causes it to harden and bind the aggregate materials together.
Hydration in concrete refers to the chemical reaction between water and cement which causes the mixture to harden and gain strength. This process is crucial for the development of the concrete's properties and durability. Proper hydration is necessary to ensure the concrete reaches its desired strength and durability.
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.
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.
all things that need to dry are based on 72 degrees concrete needs 30 days to fully cure.
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.
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.
its the calcum salts that build up soft tissue and causes it to harden
