clay fines vibration

Engineering Properties of Silt and Clay

Silt and Clay are considered to be smaller family members of soil group, Even small amounts of fines can have significant effects on the engineering properties of soils. If as little as 10 percent of the particles in sand and gravel are smaller than the No.200 sieve size, the soil can be virtually impervious, especially when the coarse grains are well graded.

Soil classification

Soil classificationis the separation of soil into classes or groups each having similar characteristics and potentially similar behaviour. A classification for engineering purposes should be based mainly on mechanical properties, e.g. permeability, stiffness, strength. The class to which a soil belongs can be used in its description.

The densification of granular soils using vibro methods ...

It is well known that the presence of silt and clay fines inhibits the physical in-situ densification of sandy soils. Experience has shown that a maximum fines content of about 15% would normally permit the performance of vibro compaction methods without the addition of stone aggregate.

WAC 296-155-66401:

Clay (fine grained soil), or soil with a high clay content, which has cohesive strength. Cohesive soil does not crumble, can be excavated with vertical sideslopes, and is plastic when moist. Cohesive soil is hard to break up when dry, and exhibits significant cohesion when submerged.

Clay, Aggregate and Concrete

influence the properties of the concrete. As the clay comes in contact with the hatch water, water molecules are drawn into the layered clay particle causing an ex­ pansion and weakening the particle. The primary in­ fluence is apparently due to the increased water demand caused by the presence of these clay fines.
