Exposed aggregate mixes are a popular option for concrete surfaces because of their attractive, natural look. The process involves pouring the concrete into a form and then removing the outer layer of cement paste to reveal the aggregate, typically gravel, sand, or crushed stone, beneath.
This gives the surface a unique texture and color that is not possible with regular concrete. Exposed aggregate mixes at Mini Cretes in Albury Wodonga are often used for driveways, patios, and walkways, as well as for pool decks, decorative walls, and other outdoor surfaces.
When choosing an exposed aggregate mix, it is important to consider the size and color of the aggregate, as well as the type of cement used in the mix, since each of these factors will affect the look and durability of the final surface. For example, a mix with a larger aggregate may be more durable, while a mix with a finer aggregate may be more aesthetically pleasing.
In addition, the type of cement used in the mix will also have an effect on the strength and color of the finished product. When mixing the concrete, it is important to ensure that the proportions of cement, aggregate, and water are correct. If the proportions are not right, the finished surface may not be as strong or long-lasting as desired.
In addition, it is important to use the right type of aggregate, as different types of aggregate may react differently to the cement and to the environment. Once the concrete has been poured and the outer layer of cement paste has been removed, the surface will need to be sealed to protect it from the elements. This can be done with a sealant or a layer of epoxy paint. The sealant or paint will also help to keep the color of the exposed aggregate consistent.
