<\/div>\nPATENTS 2017\u2013 2022<\/strong><\/p>\n no. 128 206 \/ 28.04.2017<\/p>\n The patent is subject to performing of a sort of Portland cement with addition of electrostatic precipitator dust generated in the manufacturing process of the clinker resulted as consequence of dedusting the gases exhausted from the installation of raw materials grinding and that of sintering. Physical-mechanical characteristics of electrostatic precipitator dust allow its reintroduction in cement manufacturing flow as addition at clinker grinding. The cement is obtained by concomitant grinding, as consequence of dosing in different proportions, of the clinker, blast granulated slag, gypsum and electrostatic precipitator dust up to a fineness \u2013 expressed by residue on the sieve of 90\u00b5m – of about 1.5%. The new sort has upper mechanical performances in comparison with the cement without addition of electrostatic precipitator dust.<\/p>\n no. 127 510\/ 28.04.2017<\/p>\n The patent is subject to the obtaining of a clinker of Portland cement with low consumption of thermal energy, through the additive of raw mix with a combination of mineralizer substances. The advantages of performing such a clinker are: decrease of sintering temperature for the raw mix with 70o<\/sup>C, decreasing of fuel consumption and, implicitly, decreasing of CO2<\/sub> emissions. The cement obtained with such a clinker has initial and final strengths more than of the cement obtained from clinker without mineralizers.<\/p>\n no. 130240\/30.03.2017<\/p>\n The patent is subject to a special Portland cement, with addition of barite, with screening capacity of gamma radiations. The cement is obtained by concomitant grinding, in different proportions,\u00a0of the clinker of Portland cement (with characteristics according to SR EN 197-1) with barite and gypsum up a fineness expressed by Blaine specific surface of about 3500 cm2<\/sup>\/g. Linear coefficient for gamma radiation decreasing is with 4\u202614.5% higher than that of Unitary Portland cement.<\/p>\n<\/div>\n<\/div>\n <\/p>\n BREVETE 2017 \u2013 2022<\/strong><\/p>\n nr. 132948\/28.02.2022<\/p>\n Inven\u021bia se refer\u0103 la un sistem de \u00eencapsulare a de\u0219eurilor tritiate, solide \u0219i lichide, alc\u0103tuit din material compozit \u2013 mortar fin de ciment \u0219i barier\u0103 de difuzie.
