The specific gravity of Kerosene is 0.79 g/cc The specific gravity of water is 1g/cc. Procedure for Specific Gravity Test on Cement. Step #1 : The flask must be completely dry and free of liquid and moisture before being used.
Why is kerosene used in specific gravity of cement test? Kerosene is used to determine the specific gravity of cement because when water is used while experimenting (testing), it starts to react with the cement and forms calcium oxide (CaO). This affects the experiment but kerosene does not react with cement and does not affect the experiment.

Dry and clean the specific gravity bottle and weigh it with the stopper (W₁).; Fill the specific gravity bottle with cement paste sample at least half of the bottle and weigh with stopper (W ₂).; Fill the specific gravity bottle containing the cement sample, with kerosene oil (free of water) placing the stopper and weigh it (W ₃).Until doing this, do not allow any air …
Specific directions for handling and disposing of the equipment and materials consume time and resources . Kerosene requir es extra precaution when handling, as its vapors are not pleasant,and toxicrequiring the use of a fume hood. Currently, when measuring density of cement powders, scientists often substitute kerosene
Generally, a nominal mix is prepared with the cement of specific gravity 3.15. if there is any change in this value it will affect the design mix. It may increase the water-cement ratio which will affect the workability and strength of concrete. Specific Gravity of Cement Test. Object:- To determine the specific gravity of a given cement sample.
What is the specific gravity of cement? Specific Gravity of Cement is nothing but the ratio between the volume of cement to the volume of the same quantity of water. Usually, the value lies between 3.10 – 3.16 g/cc. Some types of …
One of the methods of determining the specific gravity of cement is by the use of a liquid such as water-free kerosene, which does not react with cement. What is a specific gravity of cement? We know that specific gravity of cement or Density of cement is ranging between 3.1-3.16g/cc by this, cement is 3.16 times heavier than water of the same ...
We would like to show you a description here but the site won't allow us.
Specific gravity is an important property of cement being related to its density and viscosity. It is one of the factor to determine density of cement. If the specific gravity of cement is more than 3.19 then it has more moisture content, which will affect the mix and bonding.
Kerosene is used in specific gravity of cement because it is non-aqueous, meaning it does not contain water molecules. This makes it possible to accurately measure the weight of cement samples without taking into account the presence of water.
10. Why Kerosene is used for the Specific Gravity Test of Cement? ... So, water can't be used for cement-specific gravity tests. Watch Video: Specific Gravity Test of Cement.
Kerosene, also called naphtha, is a commonly used petroleum fuel. It is used to calculate specific gravity of cement instead of water. The value of specific gravity of kerosene or naphtha is 0.79. The kerosene or …
