<p>PURPOSE:To obtain a caking material of a large incremental strength for a long period by incorporating 11-43pts.wt. insoluble anhydrite into 100pts.wt. composition obtained by mixing slag having >=4,600cm<2>/g Brain specific surface with cement in a specified ratio. CONSTITUTION:11-43pts.wt. insoluble anhydrite is added to 100pts.wt. composition obtained by incorporating slag having >=4,600cm<2>/g Braine specific surface into cement in 1:1-3:7 ratio to prepare a caking material for sludge. Although the amt. of the caking material to be added to the silt is determined by the desired design strength, the amt. may be increased or decreased by the presence or absence of hydration impeding factors such as the contents of water and organic substances in the silt to be treated. However, when the usual silt is treated, 5- 30pts.wt. said caking material is added to 100pts.wt. silt, and mixed with a common available method to obtain improved ground having desired strength.</p> |
