Experimental Analysis of Mechanical and Material Properties of Concrete Orlik Dam After 50 Years

Popis výsledku v původním jazyce

Orlik Dam is one of the most important construction work Czech Republic. Construction of the dam began in 1956 and was completed in 1961. Orlik Dam is the largest water work in the Czech Republic and is part of the Vltava Cascade. Concrete dam is straight, gravity and is high 81,5 m and long 450 m [1]. The volume of material to produce the dam was huge, it was about 923,000 cubic meters of concrete. Great work schedule and sophisticated technological solutions, however, allowed to handle 83% displacement produced as early as 32 months [2]. For the construction of the dam to be used two mixtures - wrapping concrete B170, where was 200 kg/m3 of cement and fly ash 50 kg/m3 (replaced by 20 %) and the core concrete B80, where was 130 kg/m3 of cement and 50kg/m3 fly ash (replaced by 27.8 %) [3]. Fly ash was used due to problems with the increase in heat of hydration. The following concrete composition was analyzed material and mechanical properties.
