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

Author(s): , , ,

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 ...

Influence of thermal process on microstructural and physical properties of ambient pressure dried hydrophobic silica aerogel monoliths

Author(s): , , , , , , ,

Ambient pressure dried hydrophobic silica aerogel monoliths were prepared via simultaneous solvent exchange and surface modification in order to minimize volume shrinkage and density. At room temperature, the obtained silica ...

Preparation and Characterization of Ultralow Density Silica Aerogels by Acetonitrile Supercritical Drying

Author(s): , , ,

Ultralow density silica aerogels were formulated by sol-gel process using tetramethyl orthosilicate as the precursor. A supercritical drying step was performed using acetonitrile solvent extraction. These aerogels were found to ...

Effect of pore parameters on thermal conductivity of sintered LHP wicks

Author(s): , , ,

Through the use of the salt-leaching pore forming method, a series of sintered nickel capillary wicks with variable porosity and pore characteristics were synthesized. The thermal conductivities of these wicks (...
