What Type of Aggregate is Best for Exposed Concrete? Making the Right Choice for Driveways and Floors
Introduction
Exposed aggregate concrete is a versatile, durable, and visually appealing choice for driveways, patios, and interior floors.
A defining aspect of this type of concrete is the aggregate – the small stones, pebbles, or other materials that are embedded in the concrete.
The choice of aggregate can significantly influence the appearance, texture, and durability of the finished surface.
This article explores the types of aggregates best suited for exposed concrete and why this material is an excellent choice for driveways and floors.
I. Understanding Aggregate Choices
The choice of aggregate plays a pivotal role in determining the aesthetic and functional qualities of exposed aggregate concrete. Here’s a look at some popular options:
Crushed Stone
This is a commonly used aggregate, known for its strength and durability. It comes in a variety of sizes and colors, allowing for plenty of customization.
Gravel
Available in a variety of sizes and colors, gravel provides a rounded shape that can create a different texture and appearance in the finished concrete.
Glass
Crushed glass can add a unique, sparkling appearance to exposed aggregate concrete. It’s available in a multitude of colors and is often recycled, making it an environmentally friendly choice.
Shells
In coastal areas, crushed shells are often used as aggregate for a natural, beachy look.
II. Factors to Consider in Choosing Aggregate
When choosing the best type of aggregate for exposed concrete, several factors should be considered:
Durability

Aesthetics
The color, shape, and size of the aggregate will significantly impact the look of the finished concrete. Choose an aggregate that complements the surrounding architecture and landscape.
Texture
The aggregate will affect the surface texture of the concrete. For example, larger, rounded aggregates like pebbles will create a smoother surface, while crushed stone or glass can provide more traction.
