Abstract: Soda waste is a kind of industrial waste when the traditional soda production technology is adopted. The accumulated soda waste by the Tianjin Soda Factory only has taken places up to several square kilometers. This paper deals with a procedure to mix the soda waste with some other materials such as fly ash and concrete, to form a new type of soil for land reclamation and road foundation. The chemical contents, geotechnical properties and the environmental effect of the mixtures are studied. The bearing capacity and the field stability of the foundations made of the soda waste mixtures are tested. The research results show that the mixtures can provide enough bearing capacity for road foundation and room foundation, and is especially good for land reclamation, in which less treatment is needed. The mixtures should be used far away from water sources and farm zone. Therefore, the mixtures can be used in the coastal areas where the environmental effect of the soda waste mixtures is no worse than the local soils.

Key words: soda waste, soda waste mixture, geotechnical properties, bearing capacity, corrosion
