It is more difficult to reduce the air content in uniform

Reference no: EM13546709

Choose the correct option

It is more difficult to reduce the air content in uniform fine sands, than in well-graded soils. This is thought to be due to:

compactive energy absorbed by pore pressure changes True False

grains being moved around, but not closer together True False

water 'sticking' to the grains & holding them apart True False

large air-pockets forming which cannot be compressed True False

Both grading and plasticity affect the degree of compaction. So, a HIGHER compacted density can be achieved with:

well-graded coarse soils True False

fine soils of low plasticity True False

soils with a high clay content True False

fine soils in general True False
