Recycling and Performance Evaluation of Recycled Concrete in Construction Engineering
Abstract
aims to assess the viability of recycled concrete as a sustainable alternative to traditional concrete in construction engineering. The paper
presents a detailed methodology for the collection, preparation, and testing of recycled concrete aggregates (RCA) and the production of
recycled concrete. The performance of recycled concrete was evaluated through a series of tests measuring physical properties, mechanical
strength, and durability. The results showed that recycled concrete had slightly higher density and porosity due to the presence of old mortar,
which also led to increased water absorption. However, these values were within acceptable ranges for construction materials. In terms of
mechanical properties, recycled concrete demonstrated compressive and flexural strengths that were approximately 80-90% of conventional
concrete, which is sufficient for many non-structural applications. Durability tests revealed that recycled concrete had improved resistance to
chloride penetration and equivalent freeze-thaw resistance compared to conventional concrete, indicating its potential for use in environments
prone to these conditions.
