Multi-blend soil stabilizer

The effect of fly ash on the strength and deformation characteristics of soft clay is discussed in the paper. Lime or cement has been added as secondary constituents to further enhance self-hardening of the blended mix. For example, unconfined compression tests reveal that after two weeks of curing,...
