Behaviour of cement composites with lightweight and heavyweight aggregates at high temperatures
(Budapest University of Technology and Economics, 2017-03-24)This paper presents new results of the research of the influence of individual input components done on the behaviour of cement based composite materials exposed to high temperatures. A new approach of this research lies ... -
Thermal behaviour of metakaolin/fly ash geopolymers with chamotte aggregate
(MDPI, 2016-06-30)Geopolymers are generally appreciated for their good resistance against high temperatures. This paper compares the influence of thermal treatment with temperatures ranging from 200–1200 °C on the mechanical properties and ... -
Thermodynamic Stability of Ettringite Formed by Hydration of Ye’elimite Clinker
(Hindawi Publishing Corporation, 2016-09-08)Although the stability of ettringite has been the subject of much research, the solution is not yet fully clear. Ettringite is generally considered to be stable up to a temperature of 110°C; however, some investigators ... -
On the effect of addition of carbon nanotubes on the electric conductivity of alkali-activated slag mortars
(IOP Publishing, 2017-10-18)This paper presents basic electric properties of laboratory prepared alkali-activated composite materials on the basis of finely ground granular high furnace slag to which various quantities of carbon nanotubes (CNT) have ... -
Electrical properties of alkali-activated slag composite with combined graphite/CNT filler
(IOP Publishing Ltd., 2017-10-25)Alkali-activated industrial by-products such as blast furnace slag are known to possess properties which are comparable to or even better than those observed for ordinary Portland cement. The combination of alkali-activated ...
