  • Aggregates are nothing but  the colloidal fraction, which typically contains particles sized between 1 nm and several micrometers.
  • Sand and gravel are the most generally taken aggregates from the seabed.
  • By trailer suction hopper dredgers that are capable of transporting cargoes of up to 9,000 tonnes from offshore.
