Putty structure
A putty structure is a special, solidified form of the coherent or aggregate structure - a form of the soil structure .
A cement structure is created when primary particles of the soil are bonded at the contact points through the coating of iron oxides , carbonates (such as lime ) or organic substances.
If the water content of the soil is low (especially in sandy soils), the coherence of the primary particles is often insufficient and a cement structure that has already formed breaks down into single grain structures .
