Concrete is a mixture, not a pure substance. It is made up of various substances such as cement, water, aggregates (sand, gravel), and additives. Each of these components retains its own properties and can be physically separated from the others.
A mixture of sand and gravel is typically used in construction projects as a base material for roads, driveways, and landscaping. It provides stability and drainage while still allowing for some flexibility and movement. The specific ratio of sand to gravel can vary depending on the intended use of the mixture.
Geavel is not pure, it is an undescriptable mixture of unknown composition
Mixture
One method to separate sand and gravel is using a sieve or screen with appropriately sized openings. The mixture can be poured onto the sieve and shaken to allow the smaller sand particles to fall through while the larger gravel particles remain on top.
No. Gravel is a heterogenous mixture.

Mixture
A concrete substance is a mixture of cement, water, aggregates (such as sand and gravel), and sometimes additives. When these components are combined and allowed to harden, they form a strong and durable material commonly used in construction for building structures like sidewalks, roads, and buildings.
its homogeneous...."see-through" examples :coke, kool aid, or redbull...
A sieve or a mesh screen can be used to separate sand from gravel. The mixture is poured onto the sieve, and the smaller particles like sand will fall through, while the larger gravel particles will remain on top.
