Permeability Enhancing Mechanisms of Organic Fibers in Refractory Castables
From the drying of refractory castables, to the safety of concrete structures under fire and even to the performance of rockets¿ launching pad, the pressurization of water in partially saturated media is crucial for the explosive spalling. One of the most common strategies to decrease its likelihood is the use of organic fibers leading to a more permeable microstructure, and possibly reducing the mechanical strength at high temperatures. The aim of this study is to quantify the water migration in refractory castables with different fibers at high temperatures thanks to the high neutron attenuation of hydrogen at a speed matching the intrinsic speed of the micro-scale. The different hypothesis explaining how the fibers behave during heating can be validated providing guidelines for the selection of the best polymer as a permeability enhancing additive. Besides the intrinsic scientific interest, technological advances such as efficiency gains in the processing of refractory castables can create noticeable positive impact in different segments, as well as improving the safety of high-performance concrete structures at high temperatures, such tunnels and nuclear reactor walls.
