| چکیده | ||
| In this study, flow characteristics and compressive strength of self-compacting concrete (SCC) reinforced with steel fiber were reviewed from past 35 experimental works. Different steel fibers were used such as straight, hooked, crimped and wavy. The workability of fresh SCC was assessed via using slump flow diameter, slump flow T50, L-box, J-ring, V-funnel, and V-funnel T5 tests. Results indicate that in general, there is a slump flow diameter decrease, J-ring diameter decrease, T50 time increase and V-funnel time increase with the addition of steel fiber to the mix, depending on the type of steel fiber and mineral additives. There is a vital role of steel fiber to cause blocking. The passing ability and filling ability were found to conform to the specification limits for the SCC mixes containing fiber up to 1.5%. There is a consistent increase in the V-funnel T5 time with the increase of steel fibers in the SCC mix. Positive effect of steel fiber on compressive strength is not clear. Many parameters can govern the residual strength such as fiber parameters (mainly fiber volume, aspect ratio, geometry and surface roughness), compressive strength of control concrete and the existence of mineral fillers or admixtures. | ||
