Look up concrete in Wikipedia for detailed information.
Concrete for a foundation or floor is generally mixed in the proportion 1 part cement, 2 parts sand, and 4 parts gravel (or crushed stone). Crushed stone is better than water worn stone as its irregular shape makes for stronger concrete.
If a bag of cement is approximately 1 cu. ft., a 1:2:4 mixture calls requires 1 bag cement, 2 cu. ft. sand and 4 cu. ft. stone
Since the sand and cement fills the voids of the stone the above quantities yield 4½ cu. ft. concrete.
The concrete mixture is mixed, by hand with a shovel or in a portable powered concrete mixer, with water just sufficient to provide a workable mixture for the work in hand. Care is needed not to use too much water as this weakens the final concrete.
Reinforced concrete is just normal concrete with steel reinforement placed inside.
Most bags will make a 1/3 of a cubic foot of concrete.
you need to have a ''keyway''---that is a groove in the base concrete,can be cut in if concrete has set,if not set,oil a 2x4lightly(lightly) & imbed it into the base concrete flush.
Concrete is what you make a sidewalk from. To make concrete, you mix Portland cement, sand, gravel (aggregate) and water. The cement holds the aggregate together.
Concrete IS nature, the aggregate is crushed rock, the cement is made of natural lime and clay, mix these together with water and you get concrete.

Reinforced concrete is just normal concrete with steel reinforement placed inside.
If the correct concrete mix is used and laid properly, hot weather should not make concrete crack. Instead, it is the freeze-thaw cycle that makes concrete crack.
Commercial concrete companies make many millions/year.
Most bags will make a 1/3 of a cubic foot of concrete.
A concrete mixture of sand, cement, and small gravel is used to make the concrete from which the tubular concrete pipe is made. The pipe is made of concrete.

It is synthetic, but what we use to make concrete is natural AND synthetic.
Both glass and concrete contain sand. Sand is melted to make glass. It is mixed with aggregate (gravel) portland cement and water to make concrete.

go to lowes and buy concrete mix and get alot of water.
