Secondary title:	ǂThe ǂuse of fly ash for hydraulically bound mixtures
Secondary abstract:	The aim of my diploma paper is to evaluate the influence of amount of fly ash to the strength of the hydraulically bound mixtures. It is well known that the calcareous fly ashes express hydraulic and pozzolanic properties and can be used as hydraulic binder instead of cement for hydraulically bound mixtures for roads and other trafficked areas. Fly ashes are fine powder produced as by-products by the combustion of pulverized coal or lignite in energy generating plants and captured by mechanical or electrostatic precipitators. Its use as a binder is welcome from the environmental and economical point of view. With the laboratory investigation we tried to find out how the amount of the added fly ash influences to the strength of the hydraulically bound dolomite aggregate. Our special attention was paid to the investigation with which we try to define, how different ways of ageing and maintenance of samples during ageing influence to the mechanical characteristics of laboratory mixtures.

Abstract (ePrints):	V diplomski nalogi smo skušali ovrednotiti vpliv količine elektrofiltrskega pepela na trdnost hidravlično vezanih plasti. Znano je, da nekateri pepeli ob primernem dodatku vode po nabijanju vežejo. Zaradi te lastnosti so uporabni tudi kot stabilizacijsko sredstvo pri izdelavi hidravlično vezanih plasti. Elektrofiltrski pepeli nastajajo kot stranski produkti pri proizvodnji električne energije, zato je njihova uporaba primerna iz ekološkega, kot tudi ekonomskega vidika. V okviru raziskav smo skušali ugotoviti, kako na mehanske lastnosti mešanic, z elektrofiltrskim pepelom vezanega kamenega agregata, vplivajo količina pepela, različni načini staranja ter nega vzorcev. Poleg tega smo s testi zmrzlinske odpornosti in odpornosti proti namakanju in sušenju skušali posnemati različne spremenljive klimatske pogoje, ki so jim v naravi izpostavljene hidravlično vezane plasti cest.
