you can see the different bits and pieces of the rock
If a rock has large crystals with mixed minerals in it then it is classified as granite. It might not be this all the time.
Concrete is made from filler made of small pieces of rushed rock, gravel or sand held together with a water and Portland cement mixture. Different kinds of concrete use different ratios of the materials or even different kinds of material added to the mixture to give it strength, flexibility, durability or just to use recycled materals such as crushed glass bottles.
A mixture of minerals and other materials
Metals not plastics. What is your goal? For the most part metals with some mixture of carbon see the best results from a cryogenic treatment. However, materials such as aluminum, copper, and other metals have had excellent results as well.
A composite is any material made of more than one component. Polymer composites are composites made from polymers, or from polymers along with other kinds of materials. For more information, see the Web Links to the left of this answer.
Concrete is a mixture containing cement, sand, gravel and water.
Granite is composed of quartz. feldspar, mica and amphibole minerals. There are often other materials in the composition, but these are the main parts of granite.
Granite is neither, it is a mixture. You can see grains of different minerals in it.
Granite is a mixture
Granite is a heterogeneous mixture.
Heterogeneous mixture.
Granite is a heterogeneous mixture. This means that it is made of different substances that remain physically separate.
Granite [presumably what the questioner meant by "granile"] is a mixture, as evidenced by the presence in it of different colors in different parts.
A granite countertop is a heterogeneous mixture. Granite, the main material in a granite countertop, is a type of metamorphic rock that contains minerals such as quartz and feldspar. Quartz and feldspar are two different types of minerals which make up granite. Therefore, because there are two different types of minerals in one substance it makes it heterogeneous.

Is Granite a heterogeneous mixture or is a gold ring a heteogeneous mixture?
The solid mixture that granite is made of consists of three materials. This mixture is usually made of feldspar, mica, and quartz.
