The influence of fillers on mechanical properties of fibre-cement composites

In the frame of this project we obtained wen knowledge in the field of use of meta-kaoline and fly-ash for the production of fiber-cement composites. We also showed, that by using rheological measurements, it is possible to determine the quality of cement used for the preparation of the composites.

The influence of fillers on the mechanical properties of fiber-cement composites

The influence of the various fillers (silica fume, metakaolin and fly ash) on the mechanical properties of hardened FCC materials was investigated. Special attention has been devoted to the use of fly ash in the preparation of the composites, since it is a secondary raw material that is available from Slovenian sources – thermonuclear plants. The results indicate, that regarding the mechanical properties all of the fillers can be used without major deterioration of the mechanical properties.

Influence of various fillers on the properties of fibre-cement composites

In this work we investigated the influence of the various fillers (silica fume, metakaolin and fly ash) on the mechanical properties of hardened FCC materials. The results indicate, that regarding the mechanical properties all of the fillers can be used without major deterioration of the mechanical properties, and they also does not deteriorate the rheological properties of wet composites. The results of the industrial experiment using fly-ash as filler was also presented and the results are promising.

Pre-hydration of cement

Prehydration of Portland cement is known in the field to sometimes cause unexpected loss of performance, especially in presence of admixtures, such as slump loss, set retardation, slow strength development. Actual mechanisms are not well understood. Nanocem pre-study to examine if the general phenomenon of prehydration can be scientifically investigated (analytical tools and methods).
