Aggregate with an incredibly even sizing distribution has the most important gaps While incorporating mixture with more compact particles tends to fill these gaps. The binder need to fill the gaps among the aggregate and also paste the surfaces on the mixture collectively, and is typically the most expensive ingredient.
