Investigation of microfiber as component of cementitious complex binder

Abstract

The interaction of plasma sprayed zeolite microfiber with cementitious complex binder and with each of its components such as sodium liquid glass, metallurgical slag and calcium aluminate cement was investigated. The influence of aging and thermal treatment at 1000 °C temperature on the morphology of microfiber was analysed. Microscopic, EDS and XRD spectra analysis indicated that during the interaction of the components the surface of fibre encrusts with hydration products forming calcium aluminate, calcium aluminium silicate and sodium calcium aluminium silicates derivatives. According to the results of the experiments no erosion or destruction of the fibre aged in complex cementitious binder and calcinated at 1000 °C temperature was observed.
