Gas Permeability of Concrete with the Addition of Waste Medical Masks : Undergraduate Thesis

U ovom radu ispitivana je plinopropusnost betona koji je izrađen iskorištavanjem medicinskog otpada. Maske su izrezane na trakice i dodane u svježu mješavinu betona u svrhu ojačanja. Betonske mješavine ispitane su u svježem i očvrslom stanju. U svježem stanju izmjerena je konzinstencija, temperatura i sadržaj zraka betona. Na betonu u očvrslom stanju ispitana je plinopropusnost. Rezultati dobiveni navedenim ispitivanjem uspoređeni su sa prijašnjim ispitivanjima.In this work, the gas permeability of concrete made by utilizing medical waste was investigated. The masks were cut into strips and added to the fresh concrete mix for reinforcement purposes. The concrete mixes were tested in fresh and hardened state. The consistency, temperature and air content of the concrete were measured in its fresh state. The gas permeability was tested on concrete in the hardened state. The results obtained from the mentioned test were compared with previous tests
