In an effort to be more environmentally friendly, the construction industry is investing more in 'green' concretes and insulation materials. The purpose of this research was to create a porous foam using a geopolymer mixture and varying amounts of silica carbide sludge. By changing the amount of the sludge added, researchers could control what type of microstructure was produced. The effect of this variation on porosity and thermal properties was ...
This paper investigates the effect sulphate exposure has on the thermal conductivity and mechanical strength of low density cement based foams, with and without microfiber reinforcement. This was done by exposing these cement foams to sulfphate over 90 days. The compressive strength and flexural toughness displayed a cyclic rise and fall for the plain sample, and the opposite for the reinforced sample. The thermal conductivity showed an initial rise, but then ...
Lime-hemp concrete (LHC) is a sustainable construction material with a low environmental impact. In this study, the thermal properties of two lime-hemp mixes with varying levels of hemp were measured to analyze the material’s ability to be used on a larger scale in cold and wet climates. A TPS Thermal Constants Analyser measured the thermal properties of the lime-hemp samples using the Transient Plane Source (TPS) method. Results showed ...
Polylactide (PLA) is a biodegradable polyester with a wide range of applications in transportation and construction industries. In this study, the physical and mechanical properties of low void fraction PLA foams and high void fraction PLA composite foams were examined after their fabrication using the high-pressure foam injection molding (HPFIM) process. A thermal constants analyzer measured the thermal conductivity of the samples using the transient plane source (TPS) method. Results ...
