Soil Classification - ANSWER Is the arrangement of different soils with similar
properties into groups reflects soil's physical and mechanical properties
Soil is classified according to characteristic properties such as : - ANSWER -
Cohesion: non-cohesive soils (gravel, sand) & cohesive soils (silt, clay)
- Grain size: coarse-grained soils (sand, gravel) & fine-grained soils (silt, clay)
Particle-Size Analysis Tests : - ANSWER 1. Sieve analysis test
2. Hydrometer test
Well graded sand : - ANSWER Cu > 6 and Cc = (1-3), otherwise, poorly graded
Well graded gravel : - ANSWER Cu > 4 and Cc = (1-3), otherwise, poorly
graded
Consistency of Cohesive Soil depends on : - ANSWER - Depends on the water
content of the soil.
(At very low water contents, soil sample behaves like a solid )
(At very high water contents, may flow like a liquid)
soil water content, cohesive soil may be divided into 4 basic states : - ANSWER
- solid ( Dry )
- semi-solid ( Shrinkage Limit )
- plastic ( Plastic Limit )
- liquid ( Liquid Limit )
Plasticity Index (PI) - ANSWER PI = LL - PL
Liquid Limit Test (LL) - ANSWER The water content at the soil will just close
(0.5 inch) after 25 drops. ( WL for 25 drops)
Plastic Limit Test (PL) - ANSWER The water content at which soil crumbles
when rolled into threads 3 mm (1/8" in) in diameter.
, Shrinkage Limit Test : - ANSWER The water content of this sample if it is
saturated with water at the same volume
