Abstract

Przedmiotem zgłoszenia jest technologia zastosowania kruszywa z recyklingu do betonu w konstrukcjach żelbetowych z zastosowaniem zbrojenia rozproszonego i skład mieszanki betonowej. Istotą zgłoszenia jest zastosowanie kruszywa z recyklingu do betonu w konstrukcjach żelbetowych z zastosowaniem zbrojenia rozproszonego, poprzez zmieszanie ze spoiwem w postaci cementu, piaskiem o frakcji 0-2 mm, wodą i domieszką nowej generacji, redukującą ilość wody i uplastyczniającą, charakteryzujący się tym, że kruszywo naturalne o frakcji powyżej 2 mm jest zastąpione kruszywem z recyklingu z jednoczesnym dodaniem włókien rozproszonych w ilości od 0,5% do 2,0% wagowych w stosunku do ilości zastosowanego cementu. Włókna dodaje się na sam koniec poprzez stopniowe dozowanie. Tak przygotowaną mieszankę umieszcza się w formie do betonu, a następnie zagęszcza przy użyciu wibratorów wgłębnych lub zewnętrznych. Mieszanka betonowa zawierająca kruszywo z recyklingu betonu o frakcji od 2 do 16 mm, piasek o frakcji od 0 do 2 mm, cement CEM I 42,5 R, wodę i domieszkę nowej generacji, redukującą ilość wody i uplastyczniającą, charakteryzuje się tym, że posiada cementu w ilości 320 kg/m3, piasku w ilości 742 kg/m3, kruszywa z recyklingu betonu w ilości 1203 kg/m3, wody w ilości 128 kg/m3, domieszki Chryso Plast Omega 132 w ilości 1,75% (5,6 kg/m3) w stosunku do ilości zastosowanego cementu oraz włókien rozproszonych w ilości od 0,5% do 2!% w stosunku do ilości zastosowanego cementu.The subject of the application is the technology for using recycled aggregate in reinforced concrete structures using dispersed reinforcement and the composition of the concrete mix. The application describes the use of recycled aggregate in reinforced concrete structures using dispersed reinforcement by mixing it with a binder in the form of cement, sand with a fraction of 0-2 mm, water, and a new-generation water-reducing and plasticizing admixture. The admixture replaces natural aggregate with a fraction above 2 mm with recycled aggregate while simultaneously adding dispersed fibers in amounts ranging from 0.5% to 2.0% by weight of the cement used. The fibers are added at the very end through gradual dosing. The prepared mix is placed in a concrete mold and then compacted using internal or external vibrators. A concrete mix containing recycled concrete aggregate with a fraction from 2 to 16 mm, sand with a fraction from 0 to 2 mm, CEM I 42.5 R cement, water and a new generation water-reducing and plasticizing admixture is characterized by the fact that it contains cement in the amount of 320 kg/m3, sand in the amount of 742 kg/m3, recycled concrete aggregate in the amount of 1203 kg/m3, water in the amount of 128 kg/m3, Chryso Plast Omega 132 admixture in the amount of 1.75% (5.6 kg/m3) in relation to the amount of cement used and dispersed fibers in the amount of 0.5% to 2!% in relation to the amount of cement used.
