An Investigation of the Mechanical Properties of Recycled Aggregate Concrete with Silica Fume
This study aimed to investigate the sustainable replacement of aggregates and cement in concrete. Recycled coarse aggregate (RCA) was added as a natural coarse aggregate (NCA) substitute to 50% and silica fume (SF) as a cement substitute in 5, 10, and 15%. This has the potential to reduce material costs and at the same time have a positive impact on the environment. A single size of recycled coarse aggregates was used and four sets of concrete mixes were made. A constant water/binder ratio of 0.40 was used in all concrete mixes. The mechanical properties, including compressive strength, tensile strength, and flexural strength of concrete, have been investigated and compared to those of natural aggregate concrete (NAC). Test results showed that the SF has a positive effect on the compressive strength, tensile strength, and flexural strength if the RCA content in the recycled aggregate concrete (RAC) is approximately 50%. It was found that the use of SF 5 to 10% as a cement substitute for RAC improved the performance of concrete.
