Answer:
USCS (Unified soil classification system) are the classification of soil on the basis of size of soil, which are as follows;
Alphatetical letters are use to represent the soil size such as follows;
On the basis of above USCS classification, following alphabetical letters are used:
Soil A would be regarded as letter G, because it is coarse grain soil.
Soil B would be regarded as S as it also contains coarse grain soil of sand grade.
Soil C would regarded as letter S, because it contains most amount of sand.
Soil D would regarded as letter G due to containing most of the gravel size in it.
Answer:a
The non plasticity of soil can be determined by finding its plastic index by following formula;
Plastic index= liquid limit - plastic limit
If plastic limit would equal to zero then it signifies non plastic soil.
Answer:b
The size of gravel is about 2mm to 4mm, hence according to given sieve size chart, sieve number 10 represents size of gravel. Which means about 61%.
Answer:c
The size of sand are 0.05mm to 2mm , now according to given chart this range in between sieve number 10 to 100. And the highest content of sand are found in soil C.
Answer:d
The size of silt are 0.002 mm to 0.05mm. And the silt content of soil B are about 65%.
