Exposed Aggregate Concrete

Up until the mid 1980’s, exterior concrete driveways and patios were grey slabs with a plain stipple or broom finish. Come the mid 80’s the ready-mix concrete industry in Australia began to offer concrete with a wide range of colours and textures ( ex. Exposed Aggregate Concrete). Of these, the most popular has been patterned paving such as exposed aggregate concrete. ASP Unique Paving offers other finishes such as slate impression concrete, stenciled concrete .

The finish of exposed aggregate concrete is slip resistant, durable and decorative.

Exposed aggregate can be used with two or more colour combinations on your driveway or patio, or incorporated as a border for your paving area. The colour and texture of the finished surface of exposed aggregate concrete will depend on the colour, shape and size of the stones.

The standard stone size is 7 mm-15 mm. The concrete mix should be at least 25 and 30 mpa for polished concrete, and a maximum slump of 80. The 30 mpa will give you a higher cement content and the lower slump will prevent segregation, honeycombing and flow lines.

Why it is a good idea to use clear sealer on a Exposed Aggregate Concrete ?

Applying ASP Unique Paving clear concrete sealer to an exposed aggregate surface can improve both its performance and appearance. These sealers-typically film-forming acrylic resins-can help protect against spilling, dusting, efflorescence, stains, deicing salts, and abrasion. A sealer will also enhance the color of the aggregate, accentuating its depth and richness.

The clear sealer ASP Unique Paving use  is non-yellowing and UV resistant, repels oil, grease, water, stains and is  recoatable,

It will also give the surface a high-gloss “wet look” that deepens and enriches the color of the aggregate.

When applied professionally will protect your investment and keep it looking amazing for many years to come.

ASP UNIQUE PAVING concrete sealer is suitable for residential applications, concrete countertops, fireplace surrounds, shower panels, floor tiles, wall panels, driveways, garage floors, patios, walkways, pool decks, stucco, and concrete block.  It also creates commercial grade abrasion resistance.

Exposed Aggregate Concrete for Driveways

Exposed Aggregate Concrete is a style of concrete used in Melbourne, Victoria and Australia wide mainly for driveways but can be used for sidewalks, patios and swimming pool areas as well.

The unique appeal of exposed aggregate concrete is in its finish – exposing the small stones (pebbles) that are part of concrete mixture. This creates random patterns and a variety of colors.

Exposed aggregate concrete driveways are a type of driveway where the concrete finish is a little different from your traditional, plain concrete driveways.

Such driveways are built by washing off the skin of surface once the concrete has hardened. This washing off then exposes the main aggregates of the concrete mix that are used to build the driveways.

Exposed aggregate concrete is pre-mixed with the pebbles already in it. Once the concrete has been poured and allowed to settle, the concreters need to skillfully remove the upper layer from the top to reveal the stones. The pebbles (called aggregates, hence the name exposed aggregate concrete) are of varying sizes and colors to create a natural effect and give the driveway special depth of color and texture.

Building a driveway with exposed aggregate concrete is a skilled job, especially if the desired finish is to be achieved and future cracks avoided. We strongly recommend using an experienced professional for all work with exposed aggregate concrete.

All works carried out by ASP Unique Paving meets Australian building standards regulations. We only use Exposed aggregate concrete that is deigned to withstand heavy traffic and extreme Australian weather conditions.

Our exposed aggregate concrete driveways are exceptionally long-lasting. Additional advantages of exposed aggregate concrete include slip resistance and good look that will improve the value of your home significantly.

The History of Concrete

Concrete is the most used man-made material in the world, so common that it is easy to overlook the long history of innovation behind the modern material.

The manufacturing of modern Portland cement can be traced to 1824, when Joseph Aspdin of England patented a method of burning a mixture of limestone and clay and grinding the product into a fine powder. The name “Portland” simply refers to the color, which resembled building stones from Portland, England. While it would be many years before the standard compositions of modern Portland cements were finalized, the work of Joseph Aspdin marked the beginning of modern concrete.

The addition of steel bars to concrete compensates for concrete’s weakness in tension, and makes concrete a highly versatile building material.  There were many pioneering applications, including concrete rowboats reinforced with iron bars and mesh (Jean-Louis Lambert, France, 1848). The first reinforced concrete building is often credited to William B. Wilkinson of England in 1854, although other sources credit Francois Coignet of France in 1853. The advanced use of reinforcement is generally credited to Joseph Monier of France and the principles behind his 1867 patent for a system of reinforcing flower pots. Monier would continue to develop reinforcing systems which were applied to a great variety of structures.
