Abstract
After preparation of the raw materials with regard to composition and particle size, structural clay products are usually formed in the plastic state. This means that water is added to the raw materials to produce the proper consistency and wet strength. In this process peculiar things happen that create the really unique plasticity of clays. We find that as water is added to dry clay there is as much or more of a change in the properties of the water as there appears to be in the alteration of the clay into a plastic, formable mass. For this reason it is necessary for us to pause here to look at the structure and properties of water before discussing the interactions between clay and water in an attempt to explain plasticity.
