Description
Opis wynalazkuDescription of the invention
Przedmiotem wynalazku jest mieszanka betonowa do stosowania w budownictwie i drogownictwie.The subject of the invention is a concrete mix for use in construction and road construction.
Znana jest mieszanka betonowa, na przykład z polskiego opisu patentowego nr 163348 składająca się z cementu i piasku, która charakteryzuje się tym, że zawiera koncentrat inhibitorów korozji w postaci dwuchromianu sodu lub potasu w ilości 0,5 - 20% wagowych, fluorku wapnia w ilości 0,5 - 1,5% wagowych i dikszoptu w ilości 0,2 - 1,0% wagowych, zmieszanych z cementem w gatunku nie gorszym niż 350 w proporcji 1:1, który to koncentrat zmieszany jest następnie z cementem i piaskiem w proporcji odpowiednio 0,04:1:3.A concrete mix is known, for example from Polish patent description No. 163348 consisting of cement and sand, which is characterized in that it contains a concentrate of corrosion inhibitors in the form of sodium or potassium dichromate in the amount of 0.5 - 20% by weight, calcium fluoride in the amount of 0.5 - 1.5% by weight and dikszoptu in the amount of 0.2 - 1.0% by weight, mixed with cement of a grade no worse than 350 in the proportion of 1: 1, which concentrate is then mixed with cement and sand in the proportion respectively 0.04: 1: 3.
Inna znana mieszanka betonowa, na przykład z polskiego opisu patentowego nr 197035, która zawiera kruszywo o granulacji 0,2 - 16 mm, cement i dodatki charakteryzuje się tym, że zawiera 0,6 - 2,7% wagowych włókna stalowego ciągnionego na zimno z drutu ze stali, korzystnie niskowęglowej, klejonego pasmowo za pomocą kleju łatwo rozpuszczalnego w wodzie, korzystnie na bazie octanu winylu, a stosowane kruszywo charakteryzuje się wilgotnością względną 0,1 - 0,5%.Another known concrete mix, for example from Polish patent specification No. 197035, which contains aggregate with a granulation of 0.2 - 16 mm, cement and additives is characterized by the fact that it contains 0.6 - 2.7% by weight of cold drawn steel fiber with steel wire, preferably low carbon steel wire, glued in a strip with a water-soluble adhesive, preferably vinyl acetate based, and the aggregate used has a relative humidity of 0.1-0.5%.
Celem rozwiązania według wynalazku jest opracowanie mieszanki betonowej o wysokiej wytrzymałości - na poziomie 80 MPa, wysokiej wodoszczelności oraz odporności na korozję przy udziale kruszyw recyklowanych.The aim of the solution according to the invention is to develop a concrete mix with high strength - at the level of 80 MPa, high water resistance and corrosion resistance with recycled aggregates.
Mieszanka betonowa według wynalazku charakteryzuje się tym, że składa się z cementu CM III wymieszanego z kruszywem w stosunku 1:4, modyfikowanego bentonitu sodowego w ilości do 1% masy cementu i plastyfikatora na bazie polikarboksylanów w ilości do 2% masy cementu oraz mikrokrzemionki do 10% masy cementu. Kruszywo mineralne stanowi 25% piasku oraz 75% kruszywa mineralnego o frakcji 2 - 16 mm, w tym 40% stanowi kruszywo granitowe po recyklingu wyrobów strunobetonowych, o frakcji 8 - 16 mm.The concrete mix according to the invention is characterized by the fact that it consists of CM III cement mixed with aggregate in the ratio 1: 4, modified sodium bentonite in the amount of up to 1% of the cement weight and a plasticizer based on polycarboxylates in the amount of up to 2% of the cement weight and microsilica up to 10 % by weight of cement. Mineral aggregate constitutes 25% of sand and 75% of mineral aggregate with a fraction of 2 - 16 mm, of which 40% is granite aggregate after recycling of prestressed concrete products, with a fraction of 8 - 16 mm.
Mieszanka według wynalazku pozwala na zastosowanie w swoim składzie surowca mineralnego - kruszywa granitowego pozyskiwanego z wysłużonych konstrukcji strunobetonowych po recyklingu, przez co przy małych nakładach finansowych osiąga ona duże walory użytkowe. Poprzez zastosowanie bentonitu sodowego modyfikowanego, na przykład potasem, mieszankę cechuje bardzo duża wodoszczelność, z kolei plastyfikator ułatwia technologię wbudowania mieszanki betonowej.The mixture according to the invention allows the use of a mineral raw material in its composition - granite aggregate obtained from worn-out prestressed concrete structures after recycling, thanks to which it achieves great utility values with low financial outlays. Due to the use of sodium bentonite modified with, for example, potassium, the mixture is very watertight, while the plasticizer facilitates the technology of incorporating the concrete mixture.
