ABSTRACT

Abstract Manufacture, transport and placing of concrete on large dam sites requires a compre­ hensive technological and economical appraisal of alternative systems and local condi­ tions. Performance criteria for different concreting stages are outlined and several types of plant and equipment systems are evaluated and compared. This approach is then applied to the case of the fresh concrete production and handling at the major Three-Gorges dam project in China. Keywords: fresh concrete, transport, cranes, conveyor belts, concrete mixers, turret cranes, cable cranes, mix design, large aggregate.
