Understand the role of aggregate in concrete,
-it should be strong enough (at least stronger than the concrete you want) – weakest phase material
– its chemistry should not be very reactive – durability and dimensional stability perspective.
– size and shape should accommodate for rheology and hardened state properties of concrete
– Should cater to early age properties of concrete by providing adequate resistance against shrinkage.
Practically, anything from furnace bottom ash to lightweight pumice can be used as aggregate – it depends on what the specifications for concrete are.
It depends the nearby availability of replaceable materials as fine aggregate. Like
