Stiffens Enhancement of Hybrid Reinforced Concrete Two-Way Slabs with Slurry Infiltrated Fiber Concrete
This research presents an experimental investigation of the enhancement stiffness in R.C two-way slabs using slurry infiltrated fiber concrete (SIFCON). This study looks at how distribution of the SIFCON layer, and the steel fiber volume fractions in the tension zone in hybrid two-way slab systems affects their flexural mode. Seven identical slabs measuring 1000 × 1000 × 80 mm tested as part of the study; one slab casted with normal concrete as a reference, and the other six casted as hybrid reinforced concrete slabs (normal strength concrete with SIFCON). The slabs differed in the volumetric ratio of steel fibers but were the same size overall. The volume fraction (vf) of steel fibers used were 6 and 9%. All hybrid slabs had a uniform thickness of the SIFCON layer of 20 mm in the tension zone, with a different layout of the SIFCON layer from slab dimensions. Two slabs were casted with a layer of SIFCON applied with dimensions 1000 × 1000 × 20 mm, and two slabs were casted with a layer of SIFCON applied in the form of three strips on each side, with a 50 mm width, while the last two slabs were casted with a layer of SIFCON applied in the form of five strips on each side, with a 50 mm width. A square steel plate of 300 × 300 × 20 mm was used to apply the load, it was placed in the center of the slab. The slabs were tested as simply supported under static loads. The results demonstrated that when SIFCON was added to the two-way slabs, the stiffness values increased from 43.88 to 663.56% respectively.
