Air has a higher specific heat capacity (at 1.0035 J/(g*K)) than concrete (.880 J/(g*K)).
Specific heat capacity is the measure of the heat energy required to increase the temperature of a unit quantity of a substance by unit degree (Wikipedia). Because air requires more joules of energy per gram to raise it one degree Kelvin than concrete does, it is therefore a better insulator.
What else can I help you with?
How do you make reinforced concrete?
Reinforced concrete is just normal concrete with steel reinforement placed inside.
What is normal concrete?
Normal Concrete refers to the fresh concrete which haven't yet cured providing that there was no add mixtures/any accelerators being infused upon mixing fine aggregates, gravel and cement plus water.
What is the R-value of Normal Weight Concrete per inch of material?
Normal Weight Concrete at 150 pcf has an R value of 1.22 per inch thickness
What is rich mix concrete design compare to normal mix?
it has more cement than the normal mix
Why do you have cracks in concrete?
Concrete cracks. You can do everything right and use the best materials, it will still have hairline cracks. It's normal.
Is a rubber band an insulator or conductors?
Rubber is an insulator for normal voltages.
How do you make reinforced concrete?
Reinforced concrete is just normal concrete with steel reinforement placed inside.
What kind of houses do they have in iceland?
Normal houses of bricks, concrete, wood etc.
Why do objects float better in salt water then in normal water?
Because saltwater has a higher density. It's like if you were to try to float a rock in water and then in wet concrete, it will stay afloat on the concrete because it is more dense.
What does aerated mastoids mean?
Aerated mastoids refer to the presence of air-filled spaces within the mastoid process, which is the bony prominence located behind the ear. This condition is typically observed in imaging studies, such as CT scans, and indicates normal functioning of the mastoid air cells. Well-aerated mastoids suggest that there is no fluid accumulation or infection, often associated with healthy ear function. Conversely, poorly aerated mastoids can indicate conditions like mastoiditis or chronic ear infections.
What kind of concrete to use for crafts?
I took an art course using concrete and it was normal everyday concrete. We were making stepping stones.
What is normal concrete?

What is the normal size of a concrete block?
8"X16"
What is the R-value of Normal Weight Concrete per inch of material?
Normal Weight Concrete at 150 pcf has an R value of 1.22 per inch thickness
Does metal or foam keep water hotter longer?
In general, foam is a better insulator than metal, and so foam would be expected to keep water hotter longer under most normal circumstances.
What is rich mix concrete design compare to normal mix?
it has more cement than the normal mix
Why do you have cracks in concrete?
