Abstract
Sposób wytwarzania mieszanki betonu wysokowartościowego składającej się ze spoiwa, kruszywa, dodatków mineralnych i wody w znanych proporcjach charakteryzuje się tym, że przebiega w dwufazowym procesie mieszania, gdzie w pierwszej fazie mieszania stosowana jest domieszka napowietrzająca w ilości potrzebnej do uzyskania 5,0 ÷ 8,0% zawartości powietrza w mieszance betonowej, natomiast w drugiej fazie mieszania stosowana jest domieszka odpowietrzająca w ilości zapewniającej uzyskanie nie więcej niż 5,0% zawartości powietrza w mieszance betonowej, czas trwania pierwszej i drugiej fazy mieszania i nie może być krótszy niż 60 sekund w każdej fazie. Korzystnie na początku zwilża się kruszywo częścią wody, następnie dodaje spoiwa (cementy i dodatki), a następnie domieszki w postaci plastyfikatorów z pozostałą częścią wody. Mieszanka betonowa przeznaczona jest do realizacji konstrukcji i grubościennych murów osłonowych będących elementami specjalistycznego obiektu stanowiącego urządzenia systemu prześwietlania wagonów towarowych, a której zadaniem jest poprawa właściwości ochronnych konstrukcji.The method of producing a mixture of high-performance concrete consisting of a binder, aggregate, mineral additives and water in known proportions is characterized by the fact that it takes place in a two-phase mixing process, where in the first phase of mixing, an air-entraining admixture is used in the amount necessary to obtain 5.0 ÷ 8, 0% of the air content in the concrete mix, while in the second phase of mixing, a de-aerating admixture is used in an amount that ensures not more than 5.0% of the air content in the concrete mix, the duration of the first and second mixing phases and cannot be shorter than 60 seconds in each phase. Preferably, the aggregate is first moistened with some water, then binders (cements and additives) are added, and then admixtures in the form of plasticizers with the rest of the water. The concrete mix is intended for the implementation of structures and thick-walled curtain walls, which are elements of a specialized object constituting devices for the scanning system of freight wagons, whose task is to improve the protective properties of the structure.
