Concrete is the most preferred material used in the construction industry. Because concrete has basic ingredients that are easy to find, namely cement, coarse aggregate, fine aggregate, and water. On the other hand, the maintenance of the concrete is also easy to drive, more economical, good in compression, resistant and good fire resistance. As for construction, most people use new materials such as concrete mix because people still do not think about the use of recycled materials from the materials used in construction (recycled materials from the construction of the ruin) as ecological building , according to Akbari, 2011), one of the developing countries that has used recycled aggregates as a concrete mix is Malaysia. In addition, the use of recycled aggregates is not only applied in Malaysia, but also in developed countries such as South Africa, the Netherlands, the United Kingdom, Germany, France, Russia, Canada and Japan (Parekh and Modhera, 2002).
