To determine the specific gravity of cement, kerosene which does not recent with cement is used.
Mar 09, 2017· To find the specific gravity of cement, it is required to find the weight of a certain volume of cement to the weight an equal volume of water. Objective To determine the specific gravity of cement. It is usually used in mix proportioning calculations. Converting mass of cement to volume.
Specific gravity is normally used in mixture proportioning calculations. The specific gravity of portland cement is generally around 3.15 while the specific gravity of portland-blast-furnace-slag and portland-pozzolan cements may have specific gravities near 2.90 (PCA, 1988 [1]). Standard Test Methods
To determine the specific gravity of cement, kerosene which does not recent with cement is used (which means kerosene does not react with cement). Specific gravity is normally defined as the ratio between the weight of a given volume of material and weight of an equal volume of water.
Finding out the specific gravity is generally defined as the ratio between the mass of a specified volume of substance and weight of a corresponding volume of water. To settle the specific gravity of cement, kerosene is used. If kerosene is combined with cement, it does not make any reaction.
Why use kerosene in the test specific gravity of cement? Answer. Wiki User 01/24/2011. Kerosene, a petroleum product will not interact chemically with Portland cement - water will. ...
To determine the specific gravity of cement, kerosene which does not recent with cement is used (which means kerosene does not react with cement).Specific gravity is normally defined as the ratio between the weight of a given volume of material and weight of an equal volume of water.
To determine the specific gravity of cement, kerosene which does not recent with cement is used (which means kerosene does not react with cement).Specific gravity is normally defined as the ratio between the weight of a given volume of material and weight of an equal volume of water.
Sep 10, 2017· In general, To calculate the specific gravity of material, we use water. 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
SPECIFIC GRAVITY OF CEMENT - The Constructor. To determine the specific gravity is normally defined as the ratio between the weight of a given volume of material and weight of an equal volume of waterTo determine the specific gravity of cement, kerosene which doe snot recent with cement is used
Nov 27, 2017· Every material has its own specific gravity and the value normally varies from 0.1 to 100. The material will float on water if the value is less than 1 and will sink if the value is greater than 1. Why We Calculate Specific Gravity Of Cement: Normally we use nominal mix design based on the specific gravity of cement as 3.14.
Mainly "Specific Gravity" is the is the ratio of the density of a substance to the density of a reference substance at a fixed temperature. On the other words, it is the ratio of the mass of a substance to the mass of a reference substance. And the theme is also same for cement. Specific Gravity of cement is the ratio of the density or mass of cement to the density or mass of a reference ...
Oct 27, 2018· To #determine the #specific gravity of cement, #kerosene which does not recent with cement is used. Note: Duplicate determination of specific gravity should agree within 0.01.
The 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 ...
May 04, 2013· The kerosene or Naptha should be completely free from water. Technical Discussions. The test for finding the specific gravity of Portland cement was originally considered to be of value in detecting adulteration and under burning, but is no longer thought to be of much importance in view of the fact that other tests lead to more definite ...

Oct 15, 2015· The specific gravity of Portland cement is generally about (3.12-3.19). Cement will react with water, so to prevent this reaction kerosene should be used instead of water to be mixed with cement. Purpose: To find the specific gravity of cement. Materials: 1- Ordinary Portland cement. 2- Water. 3- Kerosene.
To 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)
To determine the specific gravity of cement. Specific gravity is defined as the ratio of the weights of a given volume of material and weight of an equal volume of water.To determine the specific gravity of cement, kerosene which does not react with cement is used.
To determine the unit weight of a substance like cement, multiply the specific gravity of the cement by the unit weight of water. gcement = 3.15 x 62.4 lb/cu ft = 196.56 lb/cu ft Bulk specific gravity of concrete materials Portland Cement 3.15 ... Fundamentals of Concrete ...
