AB  - U ovom radu su predstavljene mogućnosti povećanja hidrofobnosti površine papira nanošenjem slojeva hidrofobnog materijala na njegovu površinu. Ispitane su dve različite tehnike nanošenja stearinske kiseline, šelaka i cink-hidroksida na površinu papira. Hidrofobnost je ispitana modifikovanom metodom po Kobu, merenjem ugla kvašenja i vremena zadržavanja kapi. Prisustvo sredstava za hidrofobizaciju potvrđeno je FTIR spektroskopijom. Utvrđeno je da se, primenjenim metodama nanošenja, mnogo bolji rezultati dobijaju sa stearinskom kiselinom nego sa šelakom.
AB  - The paper shows the possibilities of increasing the hydrophobicity of the paper surface by applying layers of hydrophobic material to the surface. Various application techniques and the following substances were tested: stearic acid, shellac and zinc-hydroxide. Hydrophobicity was tested using the modified Cobb method, measuring the contact angle and drop retention time. The presence of hydrophobizing agents was confirmed by FTIR spectroscopy. It was found that the methods of applying the hydrophobizing agent, used in this work, give much better results with stearic acid, compared to shellac. This manuscript presents novel possibilities of increasing paper surface hydrophobicity by applying layers of hydrophobic material to the surface. Various layer application techniques were examined, as well as substances including: stearic acid, shellac and zinc-hydroxide. Hydrophobicity was tested using the modified Cobb method, measuring the contact angle and drop retention time. The presence of hydrophobizing agents was confirmed by FTIR spectroscopy. Based on the results achieved, it can be concluded that the methods of applying the hydrophobizing agent, used in this work, give much better results with stearic acid, compared to shellac.

AB  - Geopolymeric binders (GB) were produced using fly ash (FA) and electric arc furnace slag (EAFS). The slag has been added in the range of 0-40%. The effects of slag content on the strength, microstructure and thermal resistance were evaluated. It was found that the amount of EAFS up to 30% positively affects the strength evolution of GB. The main reaction product of FA/EAFS blends was amorphous N-(C)-A-S-H gel along with geopolymer-type gel (N-A-S-H). Thermal resistance of GB was considered from the standpoint of their mechanical and dimensional stability after heating in the temperature interval of 600800 C. The changes in mechanical and thermal properties of GB after heating are attributed to the changes in their structure. The results have shown that EAFS negatively affects the thermal resistance of GB above 600 degrees C due to the phase transition and morphological transformation of the amorphous gel phase.
