Preparation of porous foam materials at low temperature by firing northern residual soil
The pile of engineering sludge not only occupies a lot of land,but also causes pollution to the environ-ment and even threatens people's health.It is an important subject how to use the residual soil as resources.In this paper,the residual sludge of a construction site in Inner Mongolia and a construction site in Shenzhen are compared and analyzed by XRD test.It is found that the residual sludge of Inner Mongolia contained soluble substances and could be sintered and formed at a lower temperature.A porous foaming material was prepared at 880℃～900℃using Inner Mongolia residual soil,foaming agent and flux as raw materials.The influence of foaming agent and flux on the porous material is discussed.It is found that the flux and foaming agent had great influence on the foaming molding of the material.
