Arid is a landscaping term used to describe coarse-grained to medium-grained material. Varying in stone material and size, each type can have its own purpose when it comes to landscaping projects.
Aggregate
is granular material, such as sand, gravel, crushed stone, crushed hydraulic cement concrete, or iron blast furnace slag, that is used with a hydraulic cementing medium to produce concrete or mortar. Aggregates are divided into two main categories: coarse-grained aggregates and fine aggregates.The aggregate of each type is further subdivided into many types and classified according to its size. The sieve analysis technique is used to determine the gradation of aggregates for use in particular applications and for other purposes. Depending on the source of the aggregates, they can be classified into two types: natural aggregates and manufactured aggregates. Knowing the different classes of aggregates is an important step when planning a concrete construction project. The three classes of aggregates are:
- Coarse-Grained Aggregates: These are typically larger than 4.75 mm in size and are usually obtained from natural sources such as river beds or quarries.
Examples include gravel, crushed stone, and sand.
- Fine Aggregates: These are typically smaller than 4.75 mm in size and are usually obtained from natural sources such as river beds or quarries. Examples include silt, clay, and dust.
- Manufactured Aggregates: These are typically produced by crushing and processing rock or other materials. Examples include recycled concrete, slag, and synthetic materials.
