The stage of reconstruction of houses collapsed and damaged by the quake could amount to hundreds of thousands of homes and had to be rebuilt at almost the same time. This will result in a large need for building materials, thus affecting the price of building materials, as well as the demand of builders / construction workers. A major earthquake, such as the one that occurred in Yogyakarta, on May 27, 2006, has resulted in hundreds of thousands of homes severely damaged and collapsed, resulting in a large number of ruins of building materials in the form of masonry walls. The existence of waste material collapses, is a huge potential when reused as a building material through appropriate recycling technology, which can answer two problems at once that meet the needs of building materials and on the other hand can clean up the waste collapse of the building. The construction of walls from wall-crumbling powder (recycled material) is more efficient and effective than conventional wall-making systems when used for mass construction (more than 20 homes) at the same time.
