What are aggregates?

Aggregates are inert granular materials such as sand, gravel or crushed stone that account for up to 75% of the total value of concrete.

How are they classified?

Aggregates can be divided into two groups, namely natural sand or manufactured sand (i.e. crushed stones).

Cost Implications

Aggregates come in all sorts of shapes, textures and sizes. These variables are important to consider when working with aggregates as they directly influence the cost of your project. For instance, the larger and more course material demand more water to make it workable. Depending on how big a project you’re working on, the cost implications could be significant.
