    • The effect of temperature on the formation of the hydrated calcium aluminate cement structure 

      Antonovič, Valentin; Kerienė, Jadvyga; Boris, Renata; Aleknevičius, Marius (Procedia Engineering, 2013)
      The effect of temperature on the formation of the structure and phase composition of the Gorkal 70 grade calcium aluminate cement (CAC) during its hydration (W/C=1) at the temperature of +5 ºC, +20 ºC and +40 ºC is ...

    • Efficiency of removal of iron, manganese, ammonium and organic matter from groundwater 

      Albrektienė, Ramunė; Rimeika, Mindaugas (10th International Conference “Environmental Engineering” (ICEE-2017), 2017)
      The acceptable concentrations in groundwater are usually in excess of iron, ammonium and manganese. These compounds are inefficiently removed by means of ordinary technologies of ammonium ions, iron and manganese compounds ...

    • Evaluation of the influence of ultradisperse dust and carbon nanostructures on the structure and properties of gypsum binders 

      Gordina, Anastasiia; Tokarev, Yury; Yakovlev, Grigory; Kerienė, Jadvyga; Sychugov, Stanislav; Mohamed, Ali El Sayed (Procedia Engineering, 2013)
      The influence of carbon nanostructures of chemical company “Arkema” and ultradisperse metallurgical dust on the properties and structure of gypsum matrix has been studied with the help of mechanical tests, X-ray phase and ...

    • Investigation of lead and iron removal from groundwater using sapropel and quartz sand 

      Heang, Sorphea; Albrektienė, Ramunė; Paliulis, Dainius (11th International Conference “Environmental Engineering” (ICEE-2020), 2020)
      In Prey Nop district of Cambodia, a district in coastal area, it was observed that concentration of iron and lead in groundwater was higher than permissible values. Lead is a highly toxic heavy metal, while iron is an ...

    • Isolation and identification of fungi growing on fibre hemp shive based thermal insulation materials 

      Vasiliauskienė, Dovilė; Balčiūnas, Giedrius; Urbonavičius, Jaunius (Aplinkos apsaugos inžinerija: 21-osios jaunųjų mokslininkų konferencijos „Mokslas – Lietuvos ateitis“ teminė konferencija / Environmental protection engineering: 21st Conference for Junior Researchers "Science - Future of Lithuania", 2018)
      Green thermal insulation materials are ecological materials with hemp, linen, jute, wood waste, maize starch, and other types of waste added to polymer-based composites. Such kind of materials are susceptible to the microbial ...

    • Melsvabakterių biomasės kaip biotrąšos naudojimo galimybės žemės ūkio augalų augimo ir vystymosi procesams valdyti 

      Jankauskienė, Jurga; Buzytė, Kornelija; Paškauskas, Ričardas (Aplinkos apsaugos inžinerija: 24-osios jaunųjų mokslininkų konferencijos „Mokslas – Lietuvos ateitis“ teminė konferencija / Environmental protection engineering: 24th Conference for Junior Researchers "Science - Future of Lithuania", 2021)
      Žemės ūkio sektoriui tenka svarbus vaidmuo įgyvendinant Europos Sąjungos žaliojo kurso tikslus. Gausiai naudojant sintetines ir organines trąšas, gamtiniuose vandenyse pastebimas nitratų koncentracijos didėjimas. Dideli ...
