摘要：

Test results for average compressive strength of 200.81 kgF/cm(2) were obtained for 3-day age of concrete at the fraction of steel fibers equal to 2.5%; for 7-days concrete we obtained the corresponding value of 263.97 kgF/cm(2) at the fraction of steel fibers equal to 2.5%; for 14-day concrete this value was 183.84 kgF/cm(2) at the fraction of steel fibers of 7.5%; and for 21-day concrete the average compressive strength of 345.99 kgF/cm(2) was attained at the fraction of steel fibers of 7.5% steels. Test results for average tensile strength of 40.46 kgF/cm(2) were obtained for 3-day age of concrete at the fraction of steel fibers equal to 2.5%; for 7-days concrete we obtained the corresponding value of 48.95 kgF/cm(2) at the fraction of steel fibers equal to 2.5%; for 14-day concrete this value was 54.38 kgF/cm(2) at the fraction of steel fibers of 5%; and for 21-day concrete the average compressive strength of 56.27 kgF/cm(2) was attained at the fraction of steel fibers of 7.5% steels.
