Zeolites are appropriate supplementary cementitious materials in cement and concrete industry. In the present work synthetic zeolites was used like supplementary material in hardened cement paste and some properties as well as its influence on Portland ce... see more

In this paper the properties and the hydration of Portland cement pastes containing zeolitized silica fume were studied. Hydrosodalite was obtained by zeolitization of silica fume. XRD, DSC, SEM and energy-dispersive X-ray spectroscopy were used as invest... see more


The possibility to use by-product SiO2·nH2O (often called AlF3 production waste) in cement casting has been attracting the interest of researchers for many years, although high content of fluorine makes the use of amorphous SiO2 problematic. Finding the w... see more



The experimental tests established the relations of rigid mineral wool products (with different structure) macrostructure parameters with main their mechanical characteristic – compressibility. The products within the nominal density between 45 and 170&nb... see more

This paper presents the research on theestimation of macrostructure parameters in accordance with the dominated fibresorientation. During experimental tests established the relations of physicaland mechanical characteristics with structural parameters of ... see more

The results of experimental investigation of reusing concrete dust (CD), from old concrete construction demolition as cement replacement are presented in the article. Tests were conducted on cement mass by replacing 0 %-30 % of cement with CD ma... see more
