Germany/Portugal: Talleres Alquezar has been using two BHS mixers in a modular plant to produce a total volume of 400,000m3 of hydro dam concrete in Portugal since 2017. Two DKX 4.5 type twin-shaft batch mixers, each with a capacity of 4.5m3, have been integrated into the plant. Germany’s BHS says that using twin-shaft batch mixers has shown that can be utilised successfully to produce this kind of specialised concrete.
Three hydro dams are being built on the Tâmega River that are expected to generate 1760GWh for the Iberian market once they have been commissioned as part of Spanish energy group Iberdrola’s large-scale hydroelectric project in Portugal. 242,000m3 of concrete is needed in Daivões for the dam wall alone, which is planned to be 78m high and 265m long. Spain’s Talleres Alquezar is the project partner for this hydro dam. Once built, the construction in Daivões is expected to dam up to 56,200,000m3 of water.
