ABSTRACT:
A water-saturated soft soil is efficiently improved in its strength by incorporating therein an additive composed of ingredients A and B; the ingredient A comprises gypsum and the ingredient B comprises a mixture of 40-55% by weight of a Portland cement and 60-45% by weight of a water-granulated iron blast furnace slag having a particle size almost equal to or smaller than that of the Portland cement. The ratio by weight of the ingredient A to the ingredient B ranges from 10/90 to 30/70 and the total amount of the ingredients A and B used for the soft soil is sufficient to strengthen the soft soil.
