High-temperature resistance of cement composites with randomly distributed aluminium silicate fibbers
Aluminium silicate fibres are known for their low thermal conductivity and specific heat capacity, high thermal shock resistance, low weight and excellent corrosion resistance. However, their use in cement-based composites for high-temperature applications has been very limited. In this paper, the effect of randomly dispersed alumina-silicate fibres on the high-temperature resistance of cement composites is analysed as a function of the mix composition. The measurement of the basic physical, mechanical, hygric and thermal properties shows the most favourable results for the composites containing calcium aluminate cement and basalt aggregates, the fibre dosage of 1 % being an optimal solution. A comparison with the results reported by other researchers shows that in the temperature range up to 1000 °C, aluminium silicate fibres perform better than steel, glass and carbon fibres for both Portland cement and calcium aluminate cement matrices, and their effect is similar to that of basalt fibres.
期刊介绍：
ACS Central Science publishes significant primary reports on research in chemistry and allied fields where chemical approaches are pivotal. As the first fully open-access journal by the American Chemical Society, it covers compelling and important contributions to the broad chemistry and scientific community. "Central science," a term popularized nearly 40 years ago, emphasizes chemistry's central role in connecting physical and life sciences, and fundamental sciences with applied disciplines like medicine and engineering. The journal focuses on exceptional quality articles, addressing advances in fundamental chemistry and interdisciplinary research.
