Plasticity in clay
The defining mechanical property of clay is its plasticity when wet and its ability to harden when dried or fired. Clays show a broad range of water content within which they are highly plastic, from a minimum water content (called the plastic limit) where the clay is just moist enough to mould, to a maximum water content (called the liquid limit) where the moulded clay is just dry enough to ho… Webb1 juli 2012 · K 2 O.Al 2 O 3 ·6SiO 2 + 2H 2 O → Al 2 O 3 .2SiO 2 .2H 2 O + K 2 O (SiO 2) + 3SiO 2.

WebbPlasticity testing is a basic measure of the nature of fine particles of a soils, <0.425 mm. Depending on the moisture content of a soil, it will appear in one of four states; solid, semi solid, plastic and liquid. ... This is known as the plastic state. What does plasticity in clay mean? Plasticity is the outstanding property of claywater systems. WebbClay soils having high plasticity index with high liquid limit, is called highly plastic clays, sometimes called fat clays those have low values called lean or slightly plastic clays.
