The Solution of a Sample Numerical Problem Related with Laboratory Permeability Test of Two Soil Samples in Series, Finding the Head Loss (Soil Mechanics)

Hi, With this single solved example, you will refresh two concepts of soil mechanics, as follows.  How to find the equivalent permeability of linearly stacked soil samples.  How to find the hydraulic gradient in individual layers, and hence the head losses. So, let’s move to the problem and its solution. Problem In a laboratory, a

Le-Chatelier’s Apparatus- Soundness Test of Cement – Theory, Procedure and Calculation Formula

Aim: To find out the Soundness of Cement. Apparatus: Le- Ch-atelier’s Apparatus, Weighing balance, measuring cylinder, trowel, mixing pans heater, thermometer. Standard Reference:  Test is performed as per IS: 4031 (Part – 1) – 1988, Theory:  Cement of good quality does not contain the impurities like free lime, magnesia and sulphates, so this should be checked before use.
