What Form 8655 Determinations 2024

Music, hello viewers. The density of soil can be determined by various methods. In this program, we shall demonstrate the determination of dry density of soil using the sand replacement method as per the Indian Standard Code. The practice required for the conduct of this practical includes: a sand pouring cylinder, a cylindrical calibrating container, a metal tray with a hole, an excavating tool, a balanced glass plate, a metal tray, sufficient clean uniform sand passing 1mm and retained on 600 microns IS sieve, water content determination operators. To start with the practical, first, we shall determine the bulk density of the sand. For this purpose, we shall determine the volume of the calibrating container. The volume is equal to the area into height, where the area is equal to π/4 x d^2, and the value of d is equal to 10 centimeters, and the height is equal to 12.73 centimeters. The volume of the calibrating container is approximately equal to 1000 cubic centimeters. Now, fill the sand pouring cylinder with calibrating sand within about 10mm of the stop. Weigh the sand pouring cylinder with sand and record the weight before pouring, which is W1. Keep the sand pouring cylinder over the calibrating cylinder. Open the shutter and allow the sand to run out into the calibrating container until the calibrating cylinder is filled. Now, close the shutter and determine its weight. Place the sand pouring cylinder on a glass plate. Open the shutter and allow the sand to run out until no further movement of the sand takes place in the cylinder. Close the shutter and remove the sand pouring cylinder carefully. Collect the sand left on the glass plate in a container of non-weight and determine its weight. Repeat the same operations two more times, ensuring the same...
