Abstract

The subject of dissertation is a study of physic-mechanical properties and development of self-leveling polymer-cement composite of the ternary binder system PC-CAC-CS modified with chemical additives and polymeric substances. The dissertation systematically describes a four-step optimalization of the composite considering its key properties. Experimental part has been focused on monitoring the impact of composite components on selected final properties. Basic physico-mechanical, structural properties and its relations (compressive strength, porosity, flow abilities, setting times) have been analyzed for deeper understanding of the effects of individual composite components. Methods which quantify the existence of the newly formed hydration product – ettringite (XRD, SEM with EDS, calorimetry, dilatometry) has been chosen as additional study methods on selected combinations. A working prototype of self-leveling polymer-cement composite was successfully developed based on systematic process and using of testing procedures and measuring methods.

Předmětem disertační práce je studium fyzikálně-mechanických vlastností a tvorba prototypu samorozlivného, polymercementového kompozitu z oblasti ternárního pojivového systému PC-CAC-CS modifikovaného chemickými přísadami (aditivy) a polymerními látkami. Práce systematicky popisuje ve čtyřech krocích optimalizaci kompozitu s ohledem na jeho klíčové vlastnosti. Experimentální práce byla zaměřena na sledování vlivu složek kompozitu na vybrané výsledné vlastnosti a pro hlubší pochopení vlivů jednotlivých komponent systému byly prozkoumány základní fyzikálně-mechanické a strukturní vlastnosti a jejich případné závislosti (pevnost v tlaku, porozita, tokové vlastnosti, doby tuhnutí). Jako doplňkové metody studia byly na vybraných kombinacích použity metody kvantifikující existenci nově vzniklého hydratačního produktu – ettringitu (XRD, SEM s EDS, kalorimetrie, dilatometrie). Na základě systematického postupu za využití zkušebních postupů a měřících metod byl úspěšně vyvinut funkční prototyp samorozlivného, polymercementového kompozitu.
