The writer has developed a quite new construction technique of PC diaphragm wall so as to maintain high accuracy of PC wall in construction. The sequence of the construction of the PC diaphragm wall by newly developed method is as follows : 1. Excavating trench using normal fluid mud. 2. Setting of PC panels in the trench filled with bentonite slurry. 3. Adding water glass first and then cement paste in slurry, carrying out air agitation against slurry through the nozzels mounted on the end of the pipes installed in the PC panels. Slurry mixed with water grass and cement paste becomes hard clayey substance in uniform quality with high impermeability as time elapses. This paper describes factors which affect the strength of the aforesaid substance and physical property of the substance.
