Project description

The proposed study seeks to investigate key engineering and structural properties of FR-SCC and fiber-reinforced super workable concrete (FR-SWC) for infrastructure repair and construction. FR-SCC is targeted for repair of sub-structure elements, while the FR-SWC is targeted for construction operations. The FR-SWC requires some consolidation and can be used in less congested structural elements where this consolidation with SCC or FR-SCC is not required. The FR-SWC is easier to produce than FR-SCC and is more cost-effective for use in infrastructure construction.
