Both gravel and limestone are very versatile aggregates used in a variety of industries and used for many different purposes. They are often used for hardscaping to create both practical and decorative elements in a landscape. Limestone is the main component of cement which is the binding property for concreate. Gravel is also a component of concrete as well as sand to make up 85% of its composition.
Both of these aggregates can be used loose to improve drainage, acts as a filler, or create pathways in both domestic and commercial settings.
What Is Gravel?
Gravel is a mix of stones or pebbles that have been worn smooth by water, it is not any one single type of rock. It is usually found near water sources such as lakes and rivers. Gravel comes in many different types and is graded by size. In order to be classed as gravel the rock fragments must be above 2mm in diameter, anything smaller will be classed as sand.
What Is Limestone?
Unlike gravel, limestone is just one type of rock. It’s a sedimentary rock and makes up around 10% of all sedimentary rocks in the world. Limestone is also one of the rocks that can be included within gravel.
Limestone aggregates are often more jiggered and bulkier than gravel and is available in a range of sizes ranging from flat, large cut slab pavers all the way down to crushed limestone which can come as small stone which vary in size.
