What Types of Sand Aggregate Are Used in Building Projects?
What do builders mean when they use the term “sand aggregate?” In fact, it may refer to many types of sand or aggregates available for a huge range of projects. From laying concrete and building a driveway subbase to creating a garden path or a septic system, they provide the most basic building block in most outdoor home and garden projects.
Is Sand and Aggregate the Same Thing?
The term aggregate in building and landscaping refers broadly to a generally small rock fragment. Also called aggregate sand, gravel or just plain sand, the terms are often used somewhat interchangeably, although gravel is never called sand. It’s ok to refer to all these products as aggregates, although being precise can help avoid confusion.
What Are the Different Types?
Unfortunately, this also varies depending on the supplier. However, sand aggregate types can be broken down into four main groups:
- Sand
- Gravel
- Crushed stone
- Fill
Sand is used throughout building and landscaping. So is gravel. Crushed stone is most typically used as a finishing layer, since it’s more attractive, smoother and comes in a variety of shapes and colors. However, it’s also used in virtually every area of construction and industry since it can be manufactured to many different sizes and needs.
Fill is just the opposite, being made of any cheap mass, and is used anywhere that needs more bulk. Its inexpensive nature makes it an excellent choice for anything that won’t be immediately visible.
How Can You Choose the Right One?
There are so many different types that listing them all is effectively impossible. When choosing the right one for your project, you need to make a list of the desired characteristics and result, then consult with your local sand aggregate supplier to find the perfect solution.
Do you need a coarse aggregate or a smooth one? Does it need to be decorative, or can it be cheap fill? What particle size do you need? If you know the answers to all these questions, you should be ready to find the perfect sand aggregate for your project.
