Application possibilities for studies of the early hydration process of pastes in selected hydraulic, mostly cementitious materials are presented. The results obtained demonstrate, that the acoustic shear wave metod presented is quite sensitive to different parameters (composition, water/cement ration, fineness, grain size distribution, addition of additives) which influence the hydration process of these materials. Applications to curing process following, in time domain, of non-cement compounds are possible. On the basis of an evaluation of these and other experimental studies a compact 'hardness and cure meter' for industrial testing and for research will be constructed"},{"@xml:lang":"sl","#text":"V prispevku sta opisani nova naprava in metoda za neporušno sledenje hidratacije hidravličnih materialov. Naprava je osnovana na merjenju odboja ultrazvočnih strižnih valov. Prikazani rezultati meritev hidratacije, zlasti cementnih past, kažejo, da je opisana metoda zelo občutljiva na različne parametre (sestava, razmerje voda/cement, finoča, porazdelitev velikosti zrn, uporabljeni aditivi), ki vplivajo na proces hidratacije teh gradiv. Metoda je uporabna tudi za časovno sledenje procesa strjevanja drugih ne-cementnih materialov. Na osnovi evaluacije prikazanih rezultatov in meritev, ki potekajo, bo zgrajen kompaktni 'merilec hidratacije in strjevanja' za uporabo pri laboratorijski ali procesni kontroli v proizvodnji ter pri raziskavah"},{"@xml:lang":"sl","#text":"Nadaljuje se kot: Materiali in tehnologije"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-L8SGPIKK","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-L8SGPIKK"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-L8SGPIKK/bc2cb1b6-b3b9-4f14-bfaa-447c96f98de1/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Inštitut za kovinske materiale in tehnologije"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-L8SGPIKK/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-L8SGPIKK"}}}}
