Upload NowOn the basis of number and arrangement of tetrahedral and octahedral sheets, silicate clays are classified into 3-different groups: 1. 1:1 Type Clay Minerals 2. 2:1 Type Minerals 3. 2: 1:1 Type Minerals. 1. 1:1 Type Clay Minerals: Such silicate clay is made up of one silica sheet and one alumina sheet combined. In soils, […]

Grain Size Analysis of Soil
Article shared by : 
The grain size distribution of any soil can be determined using the grain size analysis, also called mechanical analysis. The basic method of mechanical analysis is to sieve the soil through a set of sieves of standard opening size. Sieve analysis can be used only for the mechanical analysis of gravel and sand as the […]
How to Conduct Tests for Fine-Grained Soils? | Soil Engineering
Article shared by :
The following manual or field tests are useful for preliminary identification of the fine-grained soil before conducting regular laboratory tests such as sieve analysis, sedimentation analysis, or tests on consistency limits. These manual tests are conducted on soils by passing them through the 425-µm IS sieve. 1. Dilatancy: i. A soil sample of volume 5 […]
