The paper deals with possibility of utilization of the fly ash from fluidal beds as the component of underwater concrete. The concrete mixes contained various amounts of the fly ash, made and cured in different conditions, including underwater environment, were tested. The rheological characteristics of the concrete mixes has covered the flow table consistence and wash-out losses after immersion in water. The compressive strength of the concrete was also determined after various time of curing. It has been found out that, under certain conditions, the fluidal fly ashes can be valuable addition to underwater concrete mixes.
