Application of expanded glass granulate and basalt fibers in the formation of lightweight cement-based refractory composite

Popis výsledku v původním jazyce

The objective of the research is to investigate the mechanical properties of the newly designed lightweight cement-based refractory composite before and after high-thermal loading. To produce convenient refractory material was chosen binder system based on aluminous cement. Lightweight composite/concrete (LWC) is an effective and easy way to deduce a dead load of the structure. Besides, LWC is mainly formed by porous materials and high content of air bubbles. That's the reason why its coefficients of heat conduction and linear expansion are smaller than that of ordinary concrete. Therefore, LWC provides better thermal conservation, high-temperature resistance, and fire endurance. The designed composite in this paper content a lightweight aggregate Liaver in combination with chopped basalt fibers and air-entraining additive to secure the necessary values of bulk density, and was therefore classified as a lightweight composite. The short fibers are also applied for the purpose to support the composite resistance to inner tension caused by high thermal loading and achieve better residual properties.
