The light weight foamed concrete has many advantages. Because there are many pores in the matrix of concrete at the viewpoint of the insulation and fire resistance. Therefore it has been used in applications requiring insulation. The insulation property of light weight foamed concrete varies according to density. Also, density is varies according to hardened matrix and
pore rate.
The purpose of the experiment is to know the thermal properties of light weight foamed concrete according to the change of density and the shape of iron plate, when heating the light weight foamed concrete. The results of this experiment are as follows. The higher density of concrete, the lower temperature of that. This tendency is not same as that of ordinary light weight foamed concrete. It seems that temperature decrease of concrete can be affected by vapor phenomenon of inner water of concrete when concrete is heated.
The specimen of density 0.9 is showed lowest temperature. Also, the perforated specimen was efficient in preventing temperature increase.
