Abstract

Nowadays, there are a lot of new construction and development, causing the high usage of concrete in the construction. Meanwhile, the amount of construction waste is also increasing due to demolition process. A lot of the construction waste can be recycled to produce the new product and the construction is a sustainable project. Concrete and ceramic are one of the construction waste can be recycled. Both of them can be the aggregate to replace the natural aggregate in concrete since we know the physical properties of both materials are hard and strong. In this research the recycled concrete and ceramic tile waste is used as coarse aggregate in the concrete mixture as the alternative material in producing normal concrete. In this study, the concrete was produced by replacing the coarse aggregate with the RCA and the ceramic waste with the replacement percentage are 25%, 35% and 45%. A few concrete testing such as concrete cube compression test and splitting tensile test has been run in order to get the mechanical properties of the concrete, compared to the normal concrete which contains 100% of natural aggregate. And other test also has been done as density test, and slump. The analysis of the mechanical performance allowed to concluding that the use of RCA and ceramic waste is similar to the normal concrete strength with the correct mix and correct percentage of replacement. It also can be concluded that the tensile strength is proportional to the compression strength.
