TI  - Effect of carbon fibers on the mechanical properties of
steam-cured concrete
AB  - While the use of the steam-curing method in the precast concrete can result in an
early high compressive strength and thus can increase the production rate of structural
elements, it should be noted that the steam-curing method has some negative
effects on the mechanical properties of concrete due to the fact that the high-temperature
steam causes micro-cracks. On the other hand, the inclusion of carbon fibers
enhanced the overall mechanical properties in terms of high tensile strength and
modulus of elasticity. This paper aimed to investigate the effect of adding carbon fibers
to steam-cured concrete. Twenty-seven cube specimens of 15 cm dimensions
were used to investigate the unit weights, the ultrasonic pulse velocity, the compressive
strength, and the split tensile strength of the concrete. Three different mixes
were made by adding carbon fibers (0%, 0.12% and 0.24%) by weight to the concrete.
Three of each were kept in a standard curing environment for 3, 7 and 28 days.
Three specimens of each mix were steam-cured for 4 hours, and three specimens
were steam-cured for 8 hours. The result showed a significant increase in the rate of
gaining compressive strength under steam-curing with an enhancement in the tensile
strength due to the presence of fibers, all without compromising the integrity of
the concrete and without increasing the amount of voids.
