Abstract

A concrete age of 3 days with normal mixture without fiber produces 152.60 kg/cm2 flexural strength, while the flexural strength of concrete with the addition of 0.50% bendrat fiber is 208.40 kg/cm2, up 37.00% from the beginning and so does the addition of wire bendrat 2.00% is an increase of 251.00 kg/cm2 64.48%. Concrete age of 14 days with normal mixture without fibers produces strong bending 202.00 kg/cm2, while the flexural strength of concrete with fiber additions of 0.50% is 276.45 kg/cm2 and so also with the addition of 2.00% bendrat wire is 336.14 kg/cm2 an increase of 66.41%. Concrete age of 28 days with normal mixture without fiber produces 240.00 kg/cm2 flexural strength, while the flexural strength of concrete with the addition of 0.50% bendrat fiber is 319.00 kg/cm2, up 33.00% from the beginning and so does the addition of wire 2.00% is an increase of 382.30 kg/cm2 59.29%. The addition of fiber wire able to dramatically increase both flexural strength of concrete at the age of 3 days and at 14 days or 28 days.
