A special kind of concrete, called air entrained concrete, was developed to overcome the problem of poor air transmission between the concrete and air. This problem occurs when a roof has insulation in place, but not reinforcement.
Without adequate support from the roof above it, hot air and rainwater will push through the insulation and into the concrete below. This will result in heat loss and theft, especially if you are high end or expensive to protect.
To remedy this issue, an Entrained Roof Cover is used. These coverings are made of heavy water resistant material that is tightly entrained within the boulder or pebble shaped concrete structure.

How does it work?
When concrete is mixed, it is placed in a tank, which is called the concrete powdering tank. This holds enough water and concrete dust to make one batch of air entrained concrete.
The main benefit of using the concrete powdering tank is that it holds enough water to ensure that the concrete binds well with itself when being poured. This helps ensure a smooth and beautiful finished product.
Another benefit is that the dust used to make the concrete can be expensively priced, which makes making your own cheaper. Using cheaper material could also improve your finished product, making it look more expensive!
How does it work? Concrete binds with itself to create what are called pockets of cement. These binded areas help create what looks like walls or a ceiling when poured.
Types of air entrained concrete
There are two main types of air entrained concrete. The first is called non-entrained concrete and the second is entrained concrete.
Non-entrained concrete typically does not require mixing, but does require a source of high stress. An example of this is when building an aircraft carrier foundation.
Enterranged concrete must be entrained in water, and can only occur when making an underwater platform or base for an object. An example of this is making a float for a swimming pool.
Making entrained concrete can be fun, if you are willing to take the time to do it! It can also provide some nice challenges, such as creating the appropriate pressure and compaction needed for setting it down.
What are the advantages of using air entrained concrete?
There are two main reasons to make air entrained concrete. The first is to make a quick, easy way to create entrained concrete. The second is to learn how to make entrained concrete!
Making entrained concrete is a fun way to do some quick construction. It is also an excellent way to learn howto make concrete as you go.
It does take some time to make entrained concrete, but not too much! Once it is made, it is made. You can either use it right away or store it for future uses.
What are the disadvantages of using air entrained concrete?
There are two main disadvantages to using air entrained concrete. The first is that it is more difficult to create patterns and patterns with this concrete. It takes a little bit of practice to figure out what colors and textures look good with the material.
The second is that it is more expensive than other types of concrete. Because the filler needs to be paid for, it is usually cost-prohibitively expensive in some places. However, if you have a strong preference for one over the other, then this may be worth it!
As mentioned before, this type of concrete can look like something out of a science fiction film or novel. If you are not comfortable with the artistic style, you can always add some gel-varnish or paint over it.
Is air entrained concrete right for me?
There are two main ways to make air entrained concrete. Both are useful, but one is better than the other. The better way is to use either a blast furnace or a random forge conflagration to produce your concrete.
The less difficult method is to use a mold to create a hollow, shape-reversible top and then pour in an entrained mixture of cement and sand. This method requires much more steps, but gives you more control over the consistency of your concrete.
Either method can be useful for several projects.
What is the cost of using air entrified concrete?
When choosing a concrete mixture, there are two main things to look for. The proportion of air and the texture.
An air-concrete has more air spaces between the concrete pieces. This creates a lighter, fluffy texture that bonds with the ground.
A more solid concrete makes more security as it does not break apart easily. An earth-tone color is better than one that is brightened by addsitive like calcium or magnesium.
Once you have chosen your mix, you must then mix it! There are many mixed-convenience products that you can buy to make this easy.
How do I make air entrained concrete?
When looking at different methods for making air entrained concrete, you should do some basic research first. What tools do you need to create air entrained concrete?
Does my tool set include a hammer? If so, it includes a nail-size hammer. If not, then I recommend buying one that does!
Does my skill set include making plaster of Paris and casting?, if so, I recommend buying the smaller size of the tool so it can be used more effectively.
How many times can I make air entrained concrete before the cement hardens and cracks?
How do I know when the cement has hardened and stayed put? When you can tell this by seeing how thick your mixture looks, hearing a noise when you push down on the handle, and/or feeling a slight shift in shape.
Choose the right mix
When concrete is being mixed, it must be forced together to create a sandwich that is filled with air. This air ensures that the concrete will harden properly and that it will not shatter when exposed to wind and rain.
There are many different mixologies for making air entrained concrete. Some recipes call for less liquid and others more. You do not need all of these ingredients if you do not have them already!
Some of the ingredients that are required in the right amount are: Portland cement, water, sand, glue, and a recipe for reinforcement. The mixture should have enough glue to completely bind the sand together, but not so much that it weakens the concrete.
Because of this requirement, some recipes require more than one bag of material per ton of concrete.
