Przedstawiono wyniki badań właściwości technologicznych i użytkowych zawiesin twardniejących z dodatkiem popiołów ze spalania fluidalnego węgla kamiennego i brunatnego. Opisano realizację doświadczalnego odcinka przesłony z zawiesiny z dodatkiem aktywowanego lotnego popiołu fluidalnego zwęgla kamiennego. Przeanalizowano i porównano wyniki testów laboratoryjnych i polowych zawiesiny użytej na przesłonę przeciwfiltracyjną modernizowanego wału przeciwpowodziowego oraz rezultaty badań in situ materiału wbudowanego w przesłonę wykonane po 1 i 7 miesiącach po realizacji obiektu.

There have been presented results of testing the technological and usable properties of the hardening suspensions with addition of ashes from fluidal combustion of the hard coal and lignite. The realization of the experimental section of a barrier made of suspension with addition of the volatile fluidal ash from the hard coal burning has been described. The laboratory and field testing of the suspension used for construction of the antifiltration barrier in the flood embankment being under modernization as well as the tests in situ of the material used for building the barrier had been carried out in 1 month and in 7 months after the object had been accomplished and the results of them have been analysed and compared.

Vertical barrier walls are widely used in environmental control systems to restrict the lateral spreading of liquid or gaseous contaminants and for seepage control through and beneath levees. The barrier walls are constructed in single or two phases using slurry composed mainly of bentonite, cementitious materials and water to maintain the trench stability and finally low hydraulic conductivity of barrier. A turning point in the development of slurry technology arose from research demonstrating the positive effects of blast furnace slag or fly-ashes on slurry properties in terms of reduced hydraulic conductivity. This paper presents the implementation of an experimental section of cut-off wall in the subsoil of a modernised flood embankment along the Vistula River and the results of controlling analyses of applied hardening slurry with an admixture of activated fluidal ashes from hard coal. The results of tests confirm the possibility of practical application of fluidal ashes as active components to hardening slurry and obtaining - depending on the suspension composition - of favourable technological and exploitation properties of this material.

Vertical barrier walls are widely used in environmental control systems to restrict the lateral spreading of liquid or gaseous contaminants and for seepage control through and beneath a levees. The barrier walls are constructed in a single or two phases using a slurry composed mainly of bentonite, cementitious materials and water to maintain the trench stability and finally low permeability of barrier. This paper presents the implementation of an experimental section of cut-off wall in the subsoil of a modemised flood embankment along the Vistula River and the results of controlling analyses of the applied hardening slurry with the admixture of activated fluidal ashes from hard coal. The results of tests confirm the possibility of practical application of fluidal ashes as active components to hardening slurry and obtaining - depending on the suspension composition - favourable technological and exploitation properties of this material.
