ADVERTISEMENTS: Introducation The behaviour of soil under external loads depends mainly on its particle size and arrangement of particles. It is therefore very important to study the size, shape and gradation of soil particles. Soil is classified on the basis of the size of their particles. The purpose of soil classification is to arrange various […]

"Cemented soil" means a soil in which the particles are held together by a chemical agent, such as calcium carbonate, such that a hand-size sample cannot be crushed into powder or individual soil particles by finger pressure. "Cohesive soil" means clay (fine grained soil), or soil with a high clay content, which has cohesive strength.
Clean, low fines gravel can only be densified with vibration and will not stand unconfined if saturated or dry. Increasing amounts of plastic fines cause increasing cohesive behavior, including dry strength and plasticity. Gravels exhibit moderate to high friability. Suitable for any type of dredge. Particularly suitable to excavation by scooping.

Clay Fines Vibration; Experimental Study on Sonic Vibration Grouting in Fine . The vibration frequency has the greatest impact on the grouting. The grouting effect is the best when the vibration frequency is close to the natural frequency of the fine silty sand. The grouting diffusion distance is getting smaller, which means the grouting effect ...
Damage Effects of Pile Driving Vibration JOHN F. WISS, Wiss, Janney, Elstner and Assoc. •PILE DRIVING, like dynamite blasts, nuclear blasts, and sonic booms, is a source of vibration which is frequently alleged to cause damage to structures. Unlike blasts, however, pile driving vibrations are produced by mechanical energy that is limited by

Clay is a finely-grained natural rock or soil material that combines one or more clay minerals with possible traces of quartz (SiO 2), metal oxides (Al 2 O 3, MgO etc.) and organic matter. Geologic clay deposits are mostly composed of phyllosilicate minerals containing variable amounts of water trapped in the mineral structure.
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.
