Three reference passive fire protection materials were tested to determine the effect that fire exposure has on their thermophysical properties. It was determined that the thermophysical properties during fire exposure have a significant impact on the performance of the materials. The knowledge of how the properties of these materials change upon exposure to fire will aid researchers in being able to better calculate the time to failure of the object ...
The authors present a method of fiber-reinforced aerogel composites by impregnation of four layers of aligned glass fibers into silica sol layer-by-layer. The effect of different fiber alignments, as well as the effect of fiber lamination on the mechanical strength of the silica aerogel composites was investigated. In addition to this, the thermal conductivity of each composite was determined. The objective of this work was to investigate whether it is ...
The effective thermal conductivities of open and closed-cell aluminium foams are measured by numerical, analytical and experimental methods. These methods are represented by the Hot Disc method, computed tomography (CT) and thermal Lattice Monte Carlo (LMC) analysis. Furthermore, the report includes experimental measurements of open-cell-M-pore and closed-cell Alporas cellular aluminium. All the results are then compared....
Since cracking in concrete is usually caused by thermal processes, relevant thermophysical properties such as heat capacity and thermal conductivity are important. This article details the measurement of thermal conductivity and heat capacity using the transient plane source method of two different (0.3 and 0.4) water-to-cement (w/c) ratio hydrated cement pastes. These thermophysical properties are measured during the initial application of the cement as well as over a period of 28 days. ...
