13-07-2017· But in cement, we use kerosene for finding specific gravity in it. The reason behind this, cement hydrates and forms calcium oxide when it reacts with water. Cement won’t show any reaction when it mixed with kerosene. The specific gravity of Kerosene is 0.79 g/cc The specific gravity of water is 1g/cc. Procedure for finding Specific gravity

MoreCement; Kerosene; OPC Cement; Le-Chatelier Flask of 250ml Or Pycnometer; Weighing Balance (Accuracy of 0.1 gm) Note Usually, water will be used as reference material for any specific gravity determinations. But as we know, the water quickly reacts with cement and forms the cement paste, which surely affects the test.

MoreSpecific Gravity of Cement. Source: commons.wikimedia.org Why We Calculate Specific Gravity of Any Substance. We calculate specific gravity of any substance to know the behavior of the material in water. And we can know the material will sink or floats in the water. All of the materials in our environment have a fixed specific gravity.

More10-03-2019· When we mixed cement with water it will easily mixed with cement then there is no chance to find the specific gravity.thats why kerosene is used for finding the specific gravity of cement. If you have another non-polar elements like kerosene we can used for the test but we can use kerosene because its available easily and economical .

More06-04-2018· AIM: To determine specific gravity of cement value APPARATUS: Le Chaterliers flask Weighing balance and kerosene (free from water). Le Chaterliers flask is made of thin glass having a bulb at the bottom. The capacity of the bulb is nearly 250 ml. The bulb is 7.8 cm in mean diameter. The stem is graduated in

MoreKerosene wets the cement well. This helps in filling all the voids in the cement. It's not that volatile. So the accuracy of measurement will be good. Above all, it does not react with cement. Water fulfills the first two conditions. But water rea...

MoreTo calculate specific gravity for any material, we have to use water. But water reacts with cement and forms calcium oxide. So that we are using Kerosene. It doesn’t react with cement. This is why we are using 0.79 g/cc (specific gravity of kerosene) in our calculation (specific gravity of water 1g/cc)

More27-11-2017· Why We Calculate Specific Gravity Of Cement: Normally we use nominal mix design based on the specific gravity of cement as 3.14. But this value will change with time if the cement is exposed to the different climatic conditions (Due to moisture content). Therefore it is very important to know the specific gravity of cement before using it in

More* Specific Gravity define by, ratio of selected fluid density to standard fluid density. * We consider standard fluid is water whose density is 1000 kg/m^3. * For kerosene. * specific gravity = density of kerosene/density of water so.. * S.G. =

MoreHere, the specific gravity of kerosene is 0.79g/cc. Note: Conduct test at least 3 times for accurate result. Clean flask before using it again. Result. The specific gravity of a sample of cement = 3.15. Why Kerosene used for Specific Gravity of Cement: If we use water instead of kerosene, water will mix with cement and make paste.

Specific Gravity of Cement SlideShare. Specific gravity is the ratio of the,To find the specific gravity of cement,, Flask

MoreWhy do we perform a specific gravity test of cement? The specific gravity of cement is tested in order to know the various atmospheric effects on the moisture content of cement. Generally, nominal Mix design is based on the value of specific gravity of cement as 3.15.

More10-03-2019· When we mixed cement with water it will easily mixed with cement then there is no chance to find the specific gravity.thats why kerosene is used for finding the specific gravity of cement. If you have another non-polar elements like kerosene we can used for the test but we can use kerosene because its available easily and economical .

MoreThis is the main reason why we ignore the use of old stock cement. Old stock cement may be affected by external moisture content. A value of specific gravity of cement greater than 3.19 shows that the cement was not properly minced into fine powder during its production or the cement

Therefore it is very important to know the specific gravity of cement before using it in

MoreThe specific gravity of portland pozzolana cement is 3.15.The specific gravity test can be done on cement using the bottle method.In this method instead of water kerosene is used to test the
