Concrete is a mix of large aggregate, small aggregate, and cement (a 4:2:1 ratio is a good approximation - though designed mixes will be more calculated than that). The size of the large aggregate isn't particularly important, unless you are working in very tight spaces or around reinforcement, in which case you want suitably small aggregate.

Recycled Aggregate

When rubble is removed from a site, it is taken to our recycling centre, where it is sorted and separated into different types of material. After the rubble is crushed, it goes through a screening process to be transformed into recycled aggregate. Read our blog to find out why 6F2 is the key to a sustainable construction.
