Conclusions 1. According to the laboratory investigations the specimens of cavitation-resistant concrete M 400, MRZ 400 containing Portland cement M 400 and gravel of the fraction up to 40 mm with the addition of GKZh-94 placed in the spillway part of the Zeya dam showed stable results of strength, frost resistance, and cavitation resistance meeting the design requirements. 2. The OVG-50 formworks for concreting the slab and RS-50 framework for the dividing wall used for constructing the spillway part of the dam provide the evenness and smoothness required by the design, are rather simple to handle, and are recommended for use. 3. With the exception of the central part, construction of the monolithic spillway bucket is possible in the OVG-50 formwork. The central part of the bucket is concreted with the use of precast reinforced beams or panel formwork. 4. The formation of the curvilinear surface of the spillway bucket from precast rein-forced-concrete beams permits simplifying concreting of the bucket with the obtainment of a good quality of the concrete surface, but further design developments are necessary for reducing the cost and metal consumption of the works.
