Aggregates must be hard, strong, chemically inert and non-porous. Organic substances and dirt coating compromise concrete strength and durability. All concrete contains natural aggregate that has been mixed into the concrete batch. This is the easiest way to choose an exposed aggregate finish, but it means you'll have to be satisfied with random placement and mixing of aggregates with less control over your finish. Lightweight aggregates can come from natural resources or can be man-made.
The main natural resource is volcanic material, while synthetic aggregates are produced by heat or heat treatment of materials with expansive properties. Recycled concrete is created by breaking, removing and crushing existing concrete to a preferred size. Commonly used as a base coat for other construction materials. Aggregates are extracted from natural sand or sand and gravel pits, hard rock quarries, dredging submerged deposits, or mining underground sediment. Reflecting the essential nature of the material, sand and gravel quarries, both in operation and defunct, are a common feature of the UK landscape, particularly in the east of England.
The wells are located in areas where glaciers left clean deposits of sand and stone. Sometimes gravel is deeper than the water table and gravel is pumped out, leaving behind ponds and lakes. Much of today's seabed was dry land 20,000 years ago, when sea levels were up to 100 m lower. After the last Ice Age, sea levels began to rise and existing river valleys, with sand and gravel deposited by glaciers, were submerged. Eventually, sea levels rose to establish the current coastline.
The ancient river sediment has been reworked by the action of the sea to leave clean and well-classified aggregates. There are different types of concrete surfaces. It pays to know which one is best for your needs before selecting the one you are going to use in your patio or driveway. The exposed aggregate is mainly recommended for families because it is non-slip, you can use it as a surface for the pool deck, patio and sidewalk. It is also an excellent choice for those who plan to improve the look of their entrance due to its resistance to heavy objects.
If you live in an area with an extreme climate, exposed aggregate is an option to consider. Can withstand high and low temperatures, even with changing weather, which can typically create problems with other types of surfaces. Those who don't like the heavy maintenance of their walkways, the exposed aggregate is an excellent choice. Aside from the occasional cleaning and sealing, you don't have to perform any other tasks to keep the surface sturdy and attractive. You can use the exposed aggregate in areas that may become slippery and damp.
It is also recommended for people looking for a decorative technique that will give them the maximum return for their money. With low maintenance and the ability to customize the look, this economical option can last a long time. Therefore, you can expect to have the same options as with the exposed aggregate, mainly with the color and stone options. However, there are a few different differences. Perhaps the biggest difference is that the sharp aggregate is deposited, which results in a much smoother finish compared to the exposed aggregate. Many homes prefer a smooth finish because it looks more elegant to them.
It also exudes an overall more expensive look. The sharp aggregate is also used in driveways because it is sturdy. However, if you consider its smooth finish, it may not be the best for this part of the property. You may want to keep the aggregate exposed, which is still thought to be the best option because of its texture. If you already have exposed aggregate, you can do it polish, which is the beauty of this type of surface.
Burnishing the existing aggregate saves you money since there is no need to remove the concrete you have installed. It's faster and much easier to update the look of your patio with this method. This type of surface is also resistant to moisture making it ideal for those areas that receive high rainfall. It offers great value for money but keep in mind that repairs can be costly. In addition, unlike the exposed aggregate, sharpened aggregate is much more expensive initially.
Like sharpened aggregate polished aggregate is a type of aggregate that is exposed or at least starts as such. This type of finish uses quartz marble or crushed granite which will go through a process to be finely ground. The mixture will be applied to the bottom and its surface will receive multiple applications to polish it. The result is a softened finish which makes plaster shine. Choosing the best aggregate for your concrete requires an understanding of how this concrete is poured and finished. The best exposed aggregate concrete will meet your color preferences and color of your surface will depend on stone you choose. If you are looking for reasons why you should choose sharpened aggregate you will be happy to know that it has almost same benefits as exposed aggregate but this sleek modern concrete finish raises difficult question: which surface will you choose? With a little research into your options you can make sure that your choice will provide long-term satisfaction.
