What are the soil classifications?

Soil classifications is a very important part of engineering. The main aim of this is to divide the broad category of soil into a small subcategory. Soil classification also helps

What is soil structure and What are its types?

Soil structure is a geometrical arrangement of particles in a soil mass. The behavior of soil depends on it. Important types of soil structures The type of soil structure depends

Seepage flow

Before discussing seepage here in this article we have already discussed about seepage in Permeability of soil and its measurement and also in seepage force. But the difference between the

What is group index of soil?

Before discussing about the Group Index (GI) we will first discuss about the need and significance of GI. Significance This group index is developed by US Bureau of Public Road.

Consistency of a clays : Atterberg Limits

This topic is bit on higher side for the readers who are interacting for the first time with soil mechanics. We define consistency by the firmness of soil in qualitative

Specific gravity of solids and its measurement

In this post we are going to learn about the physical significance of specific gravity. Further in the post we will learn most common method to determine the specific gravity

Permeability of soil and it’s measurement

The permeability of soil is soil property which describes quantitatively, the ease with which water flows through that soil. Soil consists of discrete particle. The void spaces between the particles

Water Content of soil and determination

Water content or moisture content of the soil is defined as the ratio of the weight of water to the weight of solids in a given mass of soil. It

What is void ratio?

Void ratio (e) is defined as ratio of the volume of voids to the volume of solids. $$e=\frac{V_v}{V_s}$$ where :\(V_v\) is volume of void, and \( V_s\) is volume of
