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.
Geotechnical Engineering
Geotechnical engineering is a branch of civil engineering, which deals with the engineering properties of soil. Geotechnical Engineers have to understand the situation and physical condition of the soil and based on that they have to judge the strength of the soil. So that, structural engineers can build the structure over it safely, Highway engineer can build safe roads over it.
In a nutshell “The process of understanding and working with soil and rock, underground water, site and structural conditions, concerning a construction project, is known as geotechnical engineering.”
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
Relative density of soil and its significance and limits
As the literal meaning of this word appear, relative density is the measure of looseness in relation with something. So you might be thinking why this relative word means. This
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
What actually geotechnical engineers are supposed to know?
Are you curious about geotechnical engineering, and like many others, you also wanted to start a career as Geotechnical Engineers, but don’t have enough knowledge about the geotechnical engineering? Do
