RCC Construction at Tannur Dam

Tannur Dam was the first RCC dam to be constructed in Jordan. An extensive trial mix programme was undertaken to refine and optimize the high past RCC mix. In addition, various innovations were adopted during the construction to ensure that an RCC of a consistently high quality was produced and placed. These included the use of the slope layer method of placing instead of the more conventional horizontal layer system. The outer faces of the dam were formed from grout enriched RCC (GERCC). This was introduced instead of the slip-formed facing of conventional vibrated concrete that was originally specified.
