What is the percentage of gravel content in silty clay containing gravel

Cyclic Properties of Artificially Cemented Gravel-Silty Clay …

 · This study investigated the influence of fine content and calcite cementation on the cyclic responses of artificially cemented mixed soils (CMS) and compared them with those of remolded mixed soils (RMS), which are composed of gravel-silty clay. The samples, including CMS and RMS treated with 13%, 30%, 50% and 70% fine contents, were tested.

Silt

On a volume basis a good quality soil is one that is 45% minerals (sand, silt, clay), 25% water, 25% air, and 5% organic material, both live and dead. The mineral and organic components are considered a constant with the percentages of water and air the only variable parameters where the increase in one is balanced by the reduction in the other.

What is the application of silty clay and clayey soil in civil engineering projects…

Answer (1 of 2): Cofferdams are an excellent choice of study if you want to look up uses of clay soil and silty soil in engineering. Cofferdams form temporary structures to hold back water while concrete and aggregates are placed for underwater structures.

Silty Clay

Silty clay is generally brownish gray, with soft and creamy texture, flow shape, rich in organic matter, and with clay content more than 50%. MD Ø is 8–10; QD Ø is 2–3, with medium to poor sorting; SK Ø is 0–0.1, with positive skewness. Probability curves show that it is almost composed of all suspended material.
