According to the development in the world of construction, the need for precast concrete also increases. Now the day there are many products with narrow range reinforcement and difficult dimensions. The ordinary concrete is difficult to pour in a mold with narrow range reinforcement inside without vibrator because the concrete can't fill in the gaps between the bars. SCC (Self Compacting Concrete) is a concrete that precast concrete industry needs to. The using of SCC also supports the green construction through the cement reducing and reducing the use of vibrator that requires not less energy. This research is using EFNARC standard as a condition of admission SCC (filling ability, passing ability, segregation resistance), and performed well against the application of the product by the production of Railway Sleeper without using a vibrator. The results of this study, the LB-2 and LB-3 qualified as SCC and compressive strength is expected that greater than 70 MPa, as well as products quality, is equal to standard and can be mass produced with the efficiency of the price of concrete up to 11%.
