Innovant agromaterials formulated with flax shaves and proteinic binder: Process and characterization

Agro-composite materials were produced from flax shaves and the properties of these composites were determined experimentally. The structure and morphology of the composites was determined by scanning electron microscopy (SEM), and their thermal conductivities were determined using the transient plane source method. These properties, as well as mechanical, hydric, and acoustic properties were determined as a function of the structure and size of the flax shaves....

Influence of the volume fraction and the nature of fine lightweight aggregates on the thermal and mechanical properties of structural concrete

The thermal and mechanical properties of concrete in which normal weight aggregate has been substituted with lightweight aggregates were investigated. The properties were found to be dependent on the volume fraction of the lightweight aggregate, as well as on the nature and quality of the aggregate. The addition of lightweight aggregates resulted in a decreased thermal conductivity, as well as a decreased thermal diffusivity in all samples. The compressive strength ...

Development of thermal insulating and sound absorbing agro-sourced materials from auto linked flax-tows

A rigid, self-supporting material derived from flax tow was prepared and its mechanical, thermal, hydrous, and acoustic properties were investigated. The study was performed to determine if this material would be a viable option for use as a biodegradable thermal and acoustic insulation in walls. The effect of flax-tow size after grinding on these properties was also investigated. It was determined that increasing the flax-tow size resulted in a reduction ...

The effect of silanize alumina nano-fillers addition on some physical and mechanical properties of heat cured polymethyl methacrylate denture base material 

Despite its fragility, poor thermal properties, and high water sorption rates, polymethyl methacrylate (PMMA) is commonly used in denture fabrication. This study aimed to examine how the addition of Aluminum oxide nanoparticles affected the properties of PMMA. A thermal constant analyzer measured the thermal properties of the Al2O3 nanoparticles using the transient plane source (TPS) method. Results showed that the thermal conductivity and thermal diffusivity of acrylic resin improved ...

Properties of Nanocrystals-formulated Aluminosilicate Bricks

Seven different types of nanocrystals were used as additives in aluminosilicate bricks to determine if this is a valid method of decreasing the thermal diffusivity of the bricks for use as plant coating in the iron and steel industries. Each type of nanocrystal was added in  concentration percentages of 0.5, 1, and 2 wt. % to determine the effect of concentration on thermal transport and physical properties. It was found that all of the ...
