Studying of compressive, tensile and flexural strength of concrete by using steel fibers

الملخص EN

This research aims to study the effect of adding steel fibers on the mechanical properties of concrete.

Steel fiber has a very significant effect on concrete because it delays the propagation of micro cracks that generate due to loading on concrete members such as beams and slabs, therefore ,it increases the strength of concrete.

The steel fiber was used in this study as a percentage of the volume of concrete.

Mix proportion was 1: 2 : 4 (cement: sand: gravel) by volume for all mixes and using 0 % as (control mix),0.1 %,0.2 %,0.5 % and 1.0 % of steel fibers, these ratios leads to increase the compressive, tensile ,and flexural strength of concrete, where the improvement in flexural strength was significant.
