The Longtan Hydropower Project used a lot of concrete to build a dam, with a special type called RCC making up most of it. They had to pour a lot of concrete over a long period of time, so they needed advanced equipment to handle it. The project bought top-notch equipment for making artificial aggregate, producing concrete, and moving it around. This helped them pour a huge amount of concrete each year without any issues. The project's experiences can help other big hydropower projects in the future.
