Abstract
Proizvodnja cementa čini približno 5 % globalne emisije CO2 tako što se u cementnoj peći CO2 oslobađa kalcinacijom vapnenca (2/3) i izgaranjem goriva (1/3). Nakon izlaganja zraku beton s vremenom ponovo apsorbira atmosferski CO2 koji se trajno ugrađuje. Taj proces se naziva karbonatizacija. Javlja se tijekom vremena trajanja betonske konstrukcije, ali i nakon rušenja. Beton nastao rušenjem betonskih konstrukcija odlaže se kao otpad. Njegovom ponovnom upotrebom, recikliranjem, bi se reducirao... More nastali otpad kao i korištenje prirodnog agregata za proizvodnju betona čije rudarenje iziskuje veliku potrošnju energije. To bi također imalo veliki utjecaj na prirodu, krajolik i čovjekov okoliš. Dobivanje novog betona od recikliranog betonskog agregata, koji bi zadovoljio propisane standard za konstrukcijski beton, zahtjeva primjenu tehnologije ubrzane karbonatizacije. Međutim, primjena ove tehnologije je još uvijek novost i nije do kraja razvijena. U ovom diplomskom radu je ispitan potencijal ubrzane karbonatizacije recikliranog betonskog agregata na različitim frakcijama agregata. Korištena je standardna tehnologija ubrzane karbonatizacije ugljikovim dioksidom. Na temelju mjerenja protoka plina, koncentracije CO2, relativne vlažnosti, temperature i mase napravljena je analiza podataka. Dobivena je krivulja za procjenu apsorpcije CO2 u reciklirani betonski agregat tijekom vremena za različite frakcije. Less
Abstract (english)
Cement production accounts for approximately 5 % of global CO2 emissions, by releasing CO2 in a cement kiln by calcination of limestone (2/3) and fuel combustion (1/3). After exposure to air, concrete eventually reabsorbs atmospheric CO2. This process is called carbonation. It occurs during the duration of the concrete structure, and after demolition. Concrete formed by the demolition of concrete structures is disposed of as waste. Its reuse, and recycling, would reduce the resulting waste... More and the use of natural aggregate to produce concrete whose mining requires high energy consumption. This would have a great impact on nature, the landscape, and the human environment as well. One of the possibilities for obtaining concrete from recycled concrete aggregate is the application of forced carbonation technology. However, the application of this technology is still a novelty and has not been fully developed. In this graduate thesis, the potential of accelerated carbonation of recycled concrete aggregate on different fractions of aggregates was examined. The standard technology of accelerated carbonation by carbon dioxide was used. Based on the measurement of gas flow, CO2 concentration, relative humidity, temperature, and mass, data analysis was made. A curve was obtained to assess the absorption of CO2 into a recycled concrete aggregate over time for different fractions. Less
