No, cement is a heterogeneous mixture.
Yes, the noun 'sidewalk' is a concrete noun, a word for a physical thing.
Sidewalk and driveway cement normally refers to concrete.
No, a cement sidewalk is not a homogeneous mixture because it is made up of different components like cement, sand, gravel, and water that are not uniformly distributed throughout the material. It is more accurately described as a heterogeneous mixture.
Concrete is a heterogeneous mixture. It has a no uniform composition of heavier elements that are later mixed to become evenly distributed as possible. But it is still going to be heterogeneous.

It needs to be at least 130°F (54°C) for an egg to cook on a sidewalk. The concrete's surface temperature needs to be hot enough to reach the minimum cooking temperature of an egg (around 158°F or 70°C) for it to fry.

There's less friction over a smooth concrete sidewalk
Sidewalk and driveway cement normally refers to concrete.
Sidewalk elves of course! Some of them are buried in the concrete to this day.
Concrete is a heterogeneous mixture.
When direct sunlight heats the sidewalk, the concrete material of the sidewalk absorbs the heat energy and warms up. This causes the molecules within the concrete to move faster, increasing the overall temperature of the sidewalk. The sidewalk then radiates this heat back into the environment, contributing to urban heat island effect.
