DETERMINATION OF SPECIFIC GRAVITY OF CEMENT

IS : 2720 – PART – 3


OBJECTIVE


To determine the specific gravity of cement using Le Chatelier Flask or Specific Gravity Bottle.

 

APPARATUS


1) Le Chatelier Flask or Specific Gravity Bottle – 100 ml capacity.

2) Balance capable of weighing accurately upto 0.1 gm.

 

PROCEDURE


Weigh a clean and dry Le Chatelier Flask or Specific Gravity Bottle with its stopper (W1). Place a sample of cement upto half of the flask (about 50 gm) and weight with its stopper (W2). Add kerosene (polar liquid) to cement in flask till it is about half full. Mix thoroughly with glass rod to remove entrapped air. Continue stirring and add more kerosene till it is flush with the graduated mark. Dry the outside and weigh (W3). Entrapped air may be removed by vacuum pump, if available. Empty the flask, clean it , refills with clean kerosene, flush with the graduated mark, wipe dry the outside and finally weigh (W4).

 

CALCULATION


specific gravity formula

Where, W1 = Weight of empty flask ; W2 = Weight of flask + cement ; W3 = Weight of flask + cement + kerosene ; W4 = Weight of flask + kerosene ; 0.79 = Specific gravity of kerosene

 

LIMIT


Therefore, SPECIFIC GRAVITY OF CEMENT = 3.15 g/cc

    In this grand design of things you’ll receive a B- just for effort and hard work. Where you actually confused me was first in all the particulars. You know, as the maxim goes, details make or break the argument.. And it could not be more correct right here. Having said that, let me tell you what exactly did deliver the results. Your article (parts of it) is certainly highly engaging and this is probably the reason why I am making the effort in order to opine. I do not really make it a regular habit of doing that. Second, even though I can easily notice a leaps in logic you come up with, I am not certain of how you appear to unite your ideas which in turn make the actual conclusion. For right now I will, no doubt subscribe to your point however trust in the foreseeable future you connect your facts much better.
