文摘

Dredged sediments are utilized to produce non-sintered lightweight aggregates. WLAs and WSLAs are manufactured by waterproofing and wrap-shell process. Superior performance of WSLAs is due to pozzolanic reaction of the shell layer. Silicon polymer membrane ensures WLAs equip with a hydrophobic surface. Hard concrete shell is important for non-sintered LWAs applied in harsh environment.
