Determination of Specific Gravity of Cement by Specific Gravity Bottle

OBJECT OF EXPERIMENT


The object of the experiment is to determine the Specific Gravity of Cement by Specific Gravity Bottle. Specific Gravity of cement is the ratio of the mass of unit volume of cement at a stated temperature to the mass of the same volume of gas free kerosene at a stated temperature.

APPARATUS


1. Weighing balance
2. Specific Gravity Bottle
3. Kerosene
4. Cement

PROCEDURE


1. Weight empty Specific Gravity Bottle.
Weight of Empty Specific Gravity Bottle = .................... (W1)
2. Fill the half Specific Gravity Bottle with cement and weight it.
Weight of Specific Gravity Bottle + Cement = .................... (W2)
3. Now fill the remaining half portion of Specific Gravity Bottle with Kerosene oil and weight it.
Weight of Specific Gravity Bottle + Cement + Kerosene = .................... (W3)
4. Now empty the Specific Gravity Bottle and wash it properly. Then again fill the bottle completely with Kerosene oil and weight it.
Weight of Specific Gravity Bottle + Kerosene = .................... (W4)

DATA ANALYSIS


Calculate the Specific Gravity of Cement using the following formula :

SPECIFIC GRAVITY = (W2 - W1)/(W2 - W1) - (W3 - W4) * 0.79

WHERE, 0.79 = Specific Gravity of Kerosene oil.

How to Measure Horizontal Distance Using AutoLevel Machine at Site | Learning Technology |

How to Measure Horizontal Distance Using AutoLevel Machine at Site | Learning Technology |
---------------------------------------------------------------------------------
An Autolevel machine is a professional tool generally used for accurate levelling. It is also used for measuring Horizontal distance at site. The method used to find the horizontal distance is known as 'Stadia Method'. The instrument must be used on a level surface for this method to work correctly. This Stadia range finding is good for locating topographic details such as rivers, fields, bridges, roads, and buildings.

To measure Horizontal Distance with the stadia measuring method, hold the staff rod so that it can be seen between the two stadia marks on the instrument's reticle (as pictured). With the Stadia Surveying Instrument i.e Aotolevel Machine focused on the rod, read the measurement markings on the stadia rod shown between the two stadia markings.


Say Upper Stadia Hairs =  1.63 meter       and Lower Stadia Hairs = 1.27 meter
Now Difference between Upper Stadia and Lower Stadia = 1.63 - 1.27 = 0.36 meter
Now convert the 0.36 meter into cm i.e, 0.36 x 100 = 36 cm.
In Autolevel machine, the scale of difference of Upper Stadia and Lower Stadia is designed in such a manner that it says,
1 cm = 1 m
So, we can say The horizontal distance is 36 meter.

How To Calculate The Unit Weight of M.S Angle For Billing

How To Calculate The Unit Weight of M.S Angle For Billing

MS Angles are L-shaped structural steel defined by dimension of sides & thickness. 
For Example : 20 x 20 x 3 which means, both the sides of angles are 20 mm & thickness is of 3 mm. 
There are various sizes of angles which are as follows :

The data given above is indicative. Actual weights may slightly vary. 
There is not hard rule to calculate the unit weight of Mild steel angles. 
Suppose you have 20 m M.S Angles of size 20 x 20 x 3 stacked at your site. And you want to know the total weight of M.S Angles. Then first you need to find out the unit weight of M.S Angle (20 x 20 x 3). The process of finding the unit weight is very simple. Here is a video by Er. Mukesh Sah from 
L & T - Learning Technology, explaining How to calculate the weight of M.S Angles for billing purpose.Watch the video carefully. After that multiply Total length of MS Angles (here 20 m) with unit weight to get the Total weight of M.S Angles stacked at your site.
