Not aggregate. It's plain concrete but coloured black via the 10% black oxide mix to look like below photo. We did not wanted aggregate specifically as we have it in our current house (unsealed) and find a PITA to walk on bare feet or with jandals.

 

 

The sealing will give it that shiny look much like the photo below.

 

 

The concrete path we are laying on both sides and back of the house for walking around is $92 incl GST per sqm if of below spec. This is only 100mm thick concrete and no SE665 mesh since no heavy traffic.

 

 

10% Black oxide 100mm thick concrete path. Price includes: full preparation, boxing, concrete supply and placing, concrete cutting, acid wash and seal.
