| Abstract: | Steel Fiber Reinforced Concrete(SFRC) in strength grades from CF40 to CF60 was made up by the binary superposition mix design method.The slump of the SFRC mixture was measured,and the workability and cohesiveness of the mixture were observed by the test.The results showed that the slump of SFRC mixture decreased with the increase of volume fraction of steel fiber,and increased with the increase of thickness of steel fiber wrapped slurry;the working performance of SFRC mixture was so good enough to satisfy the casting requirement of pasty concrete. |
