摘要

Macro-defect-free (MDF) cements are perspective materials providing unique properties relative to traditionalrncement pastes with great potential to incoming constructional utilization. But it is known, that MDF cementsrnexhibit sensitivity to water, with swelling and reduction of strength. This work is aimed at monitoring of anrnorganic polymer effect on the moisture resistance of MDF materials and phase changes. The effects of threerndifferent organotitanate cross-linking agents on the properties and moisture sensitivity were investigated. Thernorganotitanate-modified MDF cement samples exhibited improved moisture resistance as compared to thernstandard samples when exposed to 100 % relative humidity at 22℃. One way to eliminate the moisturernsensitivity is chemical modification of the microstructure of the MDF cements, especially polymer matrix andrnthe interphase. To increase the mechanical properties of MDF cements fibre reinforcements was used. Resultsrnshow that fibre reinforcements have positive effects on the growth of these properties.
