Strength and durability of roller compacted concrete with different types and addition rates of polypropylene fibers

Abstract Roller compacted concrete (RCC) is a relatively new alternative construction material that can be used in road and dam constructions by allowing rapid use after production and the use of conventional building materials in production. RCC, which can be produced with low water/cement ratio, i...
