Sand and gravel together

Is a concrete block a pure substance or mixture?

What is concrete . element compound mixture?

What is cement concrete?
Concrete actually contains cement as well as sand and gravel. We say "cement concrete" because cement is an ingredient in concrete. And because the cement is what binds together the sand and gravel that make up the concrete.
In a mixture of concrete there are 3lb of cement for each pound of gravel. If the mixture contains a total of 140lb of these two ingredients how many pounds of gravel are there?
The answer is 35 lbs of gravel. 140=x+3x....where x is the lbs of gravel and 3x is the lbs of cement. Therefore 140=4x....140/4=35....so x=35
Could an amorphous solid be a mixture?

What is stronger concrete or Mortar?
Concrete is stronger than mortar.Because mortar is a mixture of cement, sand and water but concrete is a mixture of cement, sand, gravel and water. Thus concrete forms a stiff mix than mortar.Hence the concrete is more stronger than cement.
Is a compound irreversible?
That depends on what is being mixed together. Two examples of this are: If you mix sand, gravel, and water it is reversible and you can separate the mixture back to its original three parts. If you mix sand, gravel, water, and cement powder it is not reversible as the water will react with the cement powder creating liquid cement and the sand and gravel will form concrete with the liquid cement. After a few hours the liquid cement in the concrete will set and the concrete mixture will become as hard as rock. It is now no longer possible to separate the mixture back to its original four parts.
