Since it is known that these active ingredients of superplasticizers can, sometimes, in varying degrees, influence the portland cement hydration process, it is important that these effects on the kinetics of portland cement hydration be determined. Here the results of an investigation into the influence of three different types of superplasticizers on the hydration processes of different portland cements are presented. The non-destructive NMR spectroscopy method was used to monitor the hydration processes. The results showed that the different active ingredients of superplasticizers for the production of concrete should always first be verified with preliminary tests</dc:description><dc:description xml:lang="sl">Superplastifikatorji se pogosto uporabljajo pri pripravi betonov. Aktivne substance superplastifikatorjev, ki so sedaj na trgu so zelo raznovrstne. Te snovi lahko tudi različno vplivajo na hidratacijske procese posameznih vrst portlandskih cementov, zato smo preučevali vpliv superplastifikatorjev različnih vrst na kinetiko hidratacije portlandskih cementov. V tem prispevku so predstavljene raziskave vpliva treh različnih superplastifikatorjev na portlandske cemente. Spremljanje procesov hidratacije smo smo opravili z nedestruktivno NMR metodo. Rezultati potrjujejo, da imajo raazlične osnovne sestavine superplastifikatorja velik vpliv na preiskušane portlandske cemente, zato mora biti kompatibilnost izbranega superplastifikatorja s portlandskim cementom za pripravo betona potrjena s predhodnimi preiskavami</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:DOC-JH74S8I2"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-JH74S8I2" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-JH74S8I2/10140b04-6ced-44e6-921c-a8d0a146380f/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Inštitut za kovinske materiale in tehnologije</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-JH74S8I2/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-JH74S8I2" /></ore:Aggregation></rdf:RDF>
