The goal of this study was to obtain information on thermal properties of three types of concrete over a wide temperature range (20°C to 800°C). The three types of concrete are: high-strength concrete (HSC), self-consolidating concrete (SCC) and fly-ash concrete (FAC). The thermal data collected included thermal conductivity, specific heat and thermal expansion of the concrete samples using the TPS method. The effect of steel, propylene and other hybrid fibers ...
The effective thermal conductivities of fully expanded intumescent chars are estimated using a finite element model related to porosity and density of the chars....
Two calcium silicate boards of different densities, porosities and pore size were analyzed for their thermal properties, specifically thermal conductivity. The boards were heated from room temperature to 400°C and the thermal conductivity was monitored during this time. A separate experiment 'aged' the boards first by heating at 1000°C for 4 hours before testing the thermal conductivity from room temperature to 400°C once again. The experimental results were compared with three ...
