The Effect of Steel Fiber on The Deflection of Self Compacted Reinforced Concrete One Way Slab With And Without Repairing

Abstract

The effect of steel fiber on the deflection of self- compacted slabs with and without repairing was investigated experimentally in this study. Three specimens were used in this study and six tests were taken. All specimens were tested under two-point loads to find the deflection of the slabs with and without repairing. The results showed that when used (0.2-0.5%Vf) steel fiber was added to concrete the deflection of the slabs decreased from (46% to 43%) to slabs without fiber under the same loads since the steel fiber increased the tensile capacity for concrete. The results also showed that the load capacity can be increased after repairing as compared with before repairing to (5.3%, 9.6%, and 17.6%)for slabs with (0,0.2 and 0.5% Vf)steel fiber respectively. On the other hand, the results were checked with the finite element method by using a sophisticated finite element program (ANSYS) and it found that the result was acceptable the difference was not more than 9%.
