Who can talk about the relationship between AB material, improved soil and ordinary soil?

AB material means that it is used after mixing. If one raw material needs to be mixed with another, directly replace one with material A and another with material B, so it is called material AB.

Improved soil can be divided into physical improved soil and chemical improved soil. Physical improvement is the improvement of changing its particle size by adding gravel, and chemical improvement is the soil that improves engineering performance by adding curing agent materials such as lime, cement and fly ash.
