Conclusions
Analysis of almost 20 years of experience with the use of roller-compacted concrete in dam construction enables us to conclude that in designing a concrete dam formed from roller-compacted concrete, it is always possible to calculate for the selection of optimal solutions, at least from a number of solutions that have been proven for other dams. Exposed trends and the most widespread conditions for use of roller-compacted concrete, including the procedural elements of its placement, require their own adjustment and adaptation in each design in conformity with the specific circumstances of the project. Despite the predominance of these trends, they should be referred to as critical, since dams formed from roller-compacted concrete are unique and should respond to specific conditions, and the selection of different solutions should correspond to technical requirements of the design. The most prevalent conditions under which roller-compacted concrete is used in dams should not therefore be considered universal; moreover, many other alternate schemes of structural and procedural solutions are also approved in actual practice.
The modern practice of constructing dams from roller-compacted concrete has accumulated a whole arsenal of proven solutions, which open broad possibilities and prospects for the design and construction of reliable structures. At the same time, it is not excluded that in a specific case, some controversial moments may arise where the placement of concrete in test blocks prior to the start of concreting for the dam will be required for its solution.
