The Enhancement of Recycled Aggregate Concrete by Steel Fiber Reinforcement for Rigid Pavement
The use of demolition waste as recycled aggregate (RA) in concrete is a high demand for sustainable developments; however, there are drawbacks to replacing RA with natural aggregate. The purpose of this study is to evaluate the application of RA to rigid pavements with steel fibers (SF) as reinforcement due to its advantages in improving tensile strength and reducing cracks. Compression tests were conducted on concrete samples cast with several contents of SF and RA to determine their desirable contents. Flexible strength was determined using the four-point bending test to show the effects of SF on the drawbacks of recycled aggregate concrete (RAC). As a result, the concrete mixture was less workable when adding SF and/ or RA. Although the compressive strength and flexure strength of RAC were subsequently decreased when a part of natural aggregate was replaced by RA, some of them were recovered after increasing a small amount of SF. In summary, it would be a possibility of applying SF to RAC pavement for lessening damages and prolong its life span.
