Design of Normal Strength Concrete Mixtures with Recycled Concrete Aggregates
This paper investigates the design of normal strength concrete mixtures that use recycled concrete aggregates as replacement for virgin natural aggregates. Three mix design methods utilizing direct weight replacement, equivalent mortar replacement, and direct volume replacement are compared based on concrete workability, compressive strength, and elastic modulus. A total of 42 mixes were made with different aggregate replacement amounts. It was determined that the concrete workability changes significantly depending on the replacement method used, with the direct volume and equivalent mortar methods resulting in the best and worst workability, respectively. The compressive strength and elastic modulus of the mixes with recycled concrete aggregates showed little variation from concrete with natural aggregates.
