A method for improving the strength of a water-saturated soft soil: premixing 5-45% by weight particulate gypsum and 55-95% by weight of a water-granulated iron blast furnace slag having a particle size of 1-100 mm to obtain a first homogeneous admixture (A) of slag particles and gypsum particles; t

A method for improving the strength of a water-saturated soft soil: premixing 5-45% by weight particulate gypsum and 55-95% by weight of a water-granulated iron blast furnace slag having a particle size of 1-100 mm to obtain a first homogeneous admixture (A) of slag particles and gypsum particles; then admixing said first admixture (A) with the soft soil to obtain a second homogeneous admixture; and then admixing (B) a Portland cement with said second admixture in an amount to provide a weight ratio of said first admixture (A) to said Portland cement (B) within the range of 75/25 to 55/45, whereby the period of time required to obtain a homogeneous mix with the soil is less than when the slag is premixed with the cement.
