 To enhance the appearance of those faces, the construction team utilized so-called grout-enriched RCC to yield a smoother face.This involved placing uncompacted RCC along the form edges, applying a neat cement grout onto the RCC surface, then vibrating the grout into the RCC to enhance a narrow zone of RCC and thus yield a smooth formed face.Komatsu and Deere loaders were used to transport the facing concrete from ready mix trucks to the locations where it was used.
