Abstract
A chemical agent for improving the engineering properties of soil includes a mixture of cementitious pozzalans (5 to 60% by mass), calcium sulphate (20 to 80% by mass), an oxide of calcium (15 to 50% by mass) and silica oxide (1 to 30% by weight). Monofilament fibers can also be included in the mix.
