W artykule przedstawiono wyniki badań cementów CEM II/A-F, zawierających jako jeden ze składników głównych drobnoziarnistą frakcję materiału pochodzącą z przemysłowej instalacji przeróbki gruzu betonowego. Materiał pozyskany z zakładu recyklingu betonu poddano mieleniu uzyskując składnik, który wg normy EN 197-6 może być określony jako składnik F. Część uzyskanego materiału poddano obróbce termicznej polegającej na prażeniu w trzech różnych temperaturach: 400°C, 600°C i 700°C. Właściwości cementów zawierających składnik F lub jego odmiany uzyskane w wyniku prażenia porównano z cementem zawierającym analogiczną dla składnika F ilość krzemionkowego popiołu lotnego. Badania wykazały pozytywny wpływ obróbki termicznej składnika F na właściwości otrzymanych spoiw pomimo stosunkowo małej zawartości stwardniałego zaczynu cementowego w użytym materiale z recyklingu betonu. Szczególnie korzystny efekt w odniesieniu do cementu referencyjnego, zawierającego popiół lotny krzemionkowy stwierdzono w przypadku użycia w składzie cementu składnika F poddanego prażeniu w temperaturze 600°C.

This paper presents the results of research on the properties of CEM II/A-F cements containing fine fraction of material from concrete rubble processing plant, as one of the main constituents of cement. The material obtained from concrete recycling plant was ground to produce a constituent that, according to EN 197-6, can be classified as constituent F. A portion of this material was further thermally processed by calcination at three different temperatures: 400°C, 600°C and 700°C. The tests demonstrated a positive influence of thermal treatment on the properties of the binders, despite the relatively low content of hardened cement paste in the recycled material. A particularly beneficial effect, relative to the reference cement containing siliceous fly ash, when constituent F calcined at 600°C was found.
