Fiber Reinforced Self-Compacting Lightweight Concrete for the Manufacture of Floating Structures

Abstract

In this study fiber reinforced self-compacting lightweight concrete prepared using polypropylene fiber, limestone dust, and lightweight expanded clay aggregate LECA. The workability of FRSCLC was evaluated using the slump flow test (with and without J-Ring), flow time (T500) with and V-funnel tests both immediate test and at time of 5 minutes. The compressive strength of cubic specimens measured at ages of 2, 7, and 28 days. Then a concrete block was designed and manufactured with expanded polystyrene block EPS100 as a core material. The test results showed successful floating concrete blocks produced with fiber reinforced self-compacting lightweight structural concrete
