    摘要: A high water content soft soil, for example from the sea or river bed, may be improved in strength by incorporating thereinto a finely divided, quenched iron blast furnace slag treated with sulfuric acid, and a Portland cement. The sulfuric acid-treated slag is a product obtained by reacting a finely divided, quenched iron blast furnace slag, such as a water-granulated iron blast furnace slag, with sulfuric acid to convert a part of its calcium components into gypsum.

    摘要: A water-saturated soft soil is efficiently improved in its strength by incorporating thereinto an additive composed of ingredients A, B and C; the ingredient A comprises gypsum, 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 and the ingredient C comprises a water-soluble ferrous salt. 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. The ingredient C is used in an amount sufficient to react with hydrogen sulfide contained in the soft soil to be treated.

    摘要: A high water content soft soil, for example from the sea or river bed, may be improved in strength by incorporating thereinto an additive composed of ingredient A including a mixture of 5-45% by weight of gypsum and 95-55% by weight of a water-granulated iron blast furnace slag having an particle size within the range of 100-1 .mu.m and ingredient B including a Portland cement. The ratio by weight of ingredient A to ingredient B is within the range of 75/25-55/45. Ingredient A is incorporated into the soft soil before incorporation of ingredient B.
