Aggregates – Types and Cost of Aggregates

Every construction requires a strong base to last a long time. Aggregate is usually used on construction sites. They are made of different materials such as sand, gravel, and crushed stone, among others. There are two main categories of aggregate names; coarse aggregate and fine aggregate.

The coarse aggregates are made up of larger particles that usually result in more economical mixes. However, if the aggregate becomes too large, it could leave a void on the structure, and that’s why this type of aggregate shouldn’t surpass 4.75mm measurement. Fine aggregates, on the other hand, are smaller, usually 9.5mm. They are mostly used to fill the voids left by the coarse aggregates and, as such, may be referred to as work ability agents. There is further categorisation of aggregate types, namely.

Secondary aggregates

These are aggregates created by leftover material at the construction site. They can concrete, bricks, sand, or asphalt. Anything that doesn’t consist of natural stone falls under this category, and for that reason, secondary aggregates will be cheaper than limestone, Granite, and gravel. They can still be used in different applications such as filling roads during construction, reinforcement of weak soil, and repair of sidewalks.

Limestone aggregates

As the name suggests, this type of aggregate is made of limestone. It is commonly used as reinforcement as well and will be found in most road construction sites as well as other structures that are made of concrete. It is cheaper than Granite.

Gravel aggregates

These aggregates are either made from gravel that is found near water bodies, or they can also be crushed from scabbled stones. They came in different sizes and preferred in construction because they are not radioactive. They are also cheaper than gravel and make high foundation reinforcement.

Granite aggregates

Granite is usually found beneath the earth’s surface and more expensive compared to the other types of aggregates. It is considered one of the most superior types, and that’s why it’s the preferred choice for those who can afford it. It doesn’t just deliver in terms of strength; it also has different colors and smooth texture that allow it to be used as a decorative feature.

Slag aggregates

These aggregates are made from crushed material that are mainly non-essential elements found at the production sites of iron and steel. The material may be collected and crushed, but they are never blasted. Sometimes they are melted and used as binding agents at the sites.

Other types of aggregates are recycled aggregates and type 1 MOT aggregates. These are made from waste material that can be recycled and Limestone and Granite particles of different sizes, respectively. They are the cheapest and will cost up to 20% less than what others cost.
