      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 ...

    • Effectiveness investigations of cleaning air from ammonia by applying a plate biofilter with a sawdust charge 

      Zagorskis, Alvydas; Leksaitis, Julius (8th International Conference “Environmental Engineering” (ICEE-2011), 2011)
      Air treatment biotechnologies are the most cost-effective and eco-friendly means of reducing the atmospheric emissions of ammonia and other odoriferous substances such as xylene, hydrogen sulphide, acetone, butanol, etc. ...

    • 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 efficiency of cassette biofilters, designed for air cleaning from xylene 

      Zagorskis, Alvydas; Spiečiūtė, Renata (8th International Conference “Environmental Engineering” (ICEE-2011), 2011)
      The experimental investigations were carried out, using the biofilter BIOF-I with the system of III cleaning stages, loaded with charge, composed of zeolite granules, wood chips, barks and foam, as well as the biofilter ...

    • 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 ...

    • Investigation of the removal of cations from aqueous solutions using sapropel 

      Albrektienė-Plačakė, Ramunė; Voišnienė, Violeta; Mucha Torre, Miguel (13th International Conference “Environmental Engineering” (ICEE-2026), 2026)
      Sapropel is a sediment found at the bottom of lakes, consisting of both organic and inorganic materials. Water contains various cations, such as ammonium, calcium, and magnesium, which are generally harmless to human health; ...

    • Modification of construction materials with multi-walled carbon nanotubes 

      Yakovlev, Grigory; Pervushin, Grigory; Maeva, Irina; Kerienė, Jadvyga; Pudov, Igor; Shaybadullina, Arina; Buryanov, Alexander; Korzhenko, Alexander; Senkov, Sergey (Procedia Engineering, 2013)
      The article presents the results of the conducted researches on modifying traditional construction materials like cement concrete, anhydrite binders, silicate paint and fire-retardant coating based on liquid glass. ...

    • Reduction of apparent water losses 

      Rimeika, Mindaugas; Albrektienė, Ramunė (10th International Conference “Environmental Engineering” (ICEE-2017), 2017)
