Common Uses Of Exposed Aggregate Concrete In Landscaping and Construction

The durability, slip resistance, and attractive, textured finish of exposed aggregate concrete make it a popular choice for landscaping and construction. Here you can see the common uses of exposed aggregate concrete in landscaping and construction.

• Driveways: Because of its strength, visual attractiveness, and non-slip surface, exposed aggregate concrete is widely used for driveways. It would be a better option for inclement weather as well and it can be helpful to manage big loads.
• Patios: Exposed aggregate concrete produces a fashionable yet practical patio floor for outdoor living areas. Well, you will consider it perfect for outdoor recreation areas as you will see that it gives outstanding traction.
• Walkways & Pathways: Garden paths, sidewalks, and walkways are frequently finished with exposed aggregate. Its organic look complements outdoor settings, and its rugged surface helps keep people from slipping & falling.
• Pool Decks: Exposed aggregate concrete provides a visually pleasing and non-slip surface around pools. It is a common material for poolside buildings due to its water resistance.
• Retaining Walls: Robust and aesthetically beautiful retaining walls can be constructed in landscaping using exposed aggregate concrete. These walls' exposed surfaces support the structure while adding texture and beauty to the design. It also functions by aiding in the control of soil erosion.

How Exposed Aggregate Concrete is Made

Exposed aggregate concrete is suitable for many uses. You can build pathways, pavements, patios and more beautiful structures. Here is how exposed aggregate concrete is made:

Mixing process

Standard concrete, consisting of cement, water, sand, and coarse aggregates such as crushed stone or gravel, is the foundation of exposed aggregate concrete. A standard ratio is followed when mixing the concrete, and consideration is given to the size and kind of particles that will be visible. You can add coloured admixtures or pigments to change the way the concrete looks in the end. So, you can enhance certain aspects of its performance, including its strength or drying time.

Types of aggregates used

Different finishes, colours, and textures can be achieved by combining different types of aggregates:

• Natural stones: Due to their smooth texture and variety of colours, river stones, granite, limestone, and quartz are frequently used.
• Crushed stones: These give the surface a more angular look and a rougher texture.
• Glass or synthetic aggregates: Recycled glass or synthetic materials can be utilised to create finishes that are distinctive and colourful, adding a decorative touch.
• Stones with colour: Stained or coloured aggregates are used to create beautiful effects that go with particular landscaping themes.

Finishing Techniques

Various techniques exist for revealing the aggregate, contingent upon the intended appearance and consistency:

• Surface Seeding: To ensure fair distribution, more aggregates are "seeded," or dispersed, on the surface and pressed into the concrete after it has been put.
• Washing and brushing: This is the most typical technique. The top layer of cement paste is scraped away with water to reveal the aggregate underneath once the concrete has half set.
• Chemical Surface Retarders: The top layer of concrete cures more slowly when a surface retarder is sprayed on it. This makes it possible for the aggregate to be seen after several hours when the top cement paste is rinsed off.
