Original Abstract
Macro-defect-free (MDF) cements are perspective materials providing unique properties relative to traditional cement pastes with great potential to incoming constructional utilization. But it is known, that MDF cements exhibit sensitivity to water, with swelling and reduction of strength. This work is aimed at monitoring of an organic polymer effect on the moisture resistance of MDF materials and phase changes. The effects of three different organotitanate cross-linking agents on the properties and moisture sensitivity were investigated. The organotitanate-modified MDF cement samples exhibited improved moisture resistance as compared to the standard samples when exposed to 100 % relative humidity. One way, how to eliminate the moisture sensitivity, is chemical modification the microstructure of the MDF cements, especially polymer matrix and the interphase. To increase the mechanical properties of MDF cements the fibre reinforcements were used. Results show that fibre reinforcements have positive effects on the growth of these properties.
