Analysis Waste Material of Construction on Concrete Column

Abstract High-rise buildings (multi-storey buildings) are currently increasing in development, accordance with their functions as apartments, offices, shopping centers or educational activities. In the implementation of high-rise building construction involves a lot resources. One resources needed large quantities is material. process implementing construction, addition to results obtained buildings, but during it produces waste Waste material generated not only affects productivity project, also environment. Therefore, necessary identify amount especially column structure work buildings. The purpose this study was determine projects, reinforced concrete structures object research project one University city Makassar. identification done through literature review, observation and secondary data. variables reviewed wood, reinforcing steel, concrete, bendrat wire. sampling method purposive sampling. showed that most form wood used formwork. percentage comes from use formwork around 21.9%. Furthermore, originating steel ranges 0.06% 0.40%. main cause formwork, indicated demolition good, so cannot be more than twice.
