Summary: | This study has been carried out to investigate the effect of the thermal conductivity of foaming gas and cement type on that of foamed concrete. The results show that the foamed concrete employed a gas having lower thermal conductivity as foaming gas or prepared from a type of cement with lower thermal conductivity takes on lower thermal conductivity. And the thermal conductivity of foamed concrete is directly proportional to the thermal conductivity of foaming gas. In addition, with the length of age, the thermal conductivity of the foamed concrete whose foaming gas is not air gradually approaches to those using air as foaming gas at the initial stage. Using the foaming gas or cement with lower thermal conductivity to prepare foamed concrete may be a feasible as well as effective way to improve the thermal insulation of foamed concrete. |
