What are the properties of clay, and what are the properties & structure of loam soils. you don’t need to answer all of them, just at least the properties, thanks.

These properties include: cation exchange capabilities, plastic behaviour when wet, catalytic abilities, swelling behaviour, and low permeability. (clay)

f sand (particle size > 63 micrometres (0.0025 in)), silt (particle size > 2 micrometres (7.9×10−5 in)), and a smaller amount of clay (particle size < 2 micrometres (7.9×10−5 in)). By weight, its mineral composition is about 40–40–20% concentration of sand–silt–clay, respectively. (Soil)
