RESEARCH TOPICS Research title Use of phase change

It has a skeleton density of approximately 2200 kg/m 3 but the high porosity can result in a bulk density as low as 3 kg/m Current aerogels for building appliions have an overall density of 70–150 kg/m3 Silica aerogels are also load bearing with a high compression strength up to 3 bar but they have a very low tensile

Coefficient of Thermal Diffusivity of Insulation Brick

20141229 This paper presents an experimental result on the effect of particle size of a mixture of ball clay kaolin and sawdust on thermal diffusivity of ceramic bricks A mixture of dry powders of ball clay kaolin of the same particle size and sawdust of different particle sizes was mixed in different proportions and then compacted to high pressures before being fired to 950#xb0C
