Where, Specific gravity of Kerosene = 0.79 g/cc.Ī good cement should have the Specific gravity of 3.1-3.6 g/cc. Empty the flask and fill the bottle with kerosene up to the tip of the bottle and record the weight as W 4.Mix thoroughly and see that no air bubbles left in the flask. Now pour kerosene in the sample up to the neck of the bottle.Now weight the Flask with the stopper as W 2 Take 50gm of cement and add it in Flask.Now, weigh the empty flask and note it as W 1.

The Lechatlier flask should be free from moisture content, that mean flask is thoroughly dried.The specific gravity of water is 1g/cc Procedure for finding Specific gravity in cement:.

The specific gravity of Kerosene is 0.79 g/cc Cement won’t show any reaction when it mixed with kerosene. The reason behind this, cement hydrates and forms calcium oxide when it reacts with water. But in cement, we use kerosene for finding specific gravity in it. In general, To calculate the specific gravity of material, we use water. Why is kerosene used in the Specific gravity of cement test? Specific Gravity Bottle capacity of 250 ml with stopper. Apparatus Required for Le Chatelier’s Principle:-ģ.

And the IS code for Specific gravity test is IS 2720- Part 3. Specific gravity test /Density of Cement test :Īs per Le Chatelier’s Principle, Specific gravity of cement is determined by Le Chatelier’s Flask method. As per IS Cement is re-tested for Specific gravity test if it is three months older. The reason for finding a lot of lumps in old cement is due to the presence of excessive moisture content in it. Cement becomes useless once it is hydrated with water. Cement undergoes a chemical reaction when it is reacted with the atmospheric moisture this process is termed as hydration. If the specific gravity is 3.19, then the pores in cement are filled with the moisture content. If the cement is exposed to extreme moisture content due to bad weather conditions, then the specific gravity of cement may go up to 3.19. For Nominal mix design, the specific gravity of cement should be 3.15g/cc.Įvery material has pores which may contain voids in it. 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 volume.Įxcessive presence of moisture content in cement effects Workability and strength of cement. If the material has a specific gravity greater than 1, then it sinks in water. If the specific gravity of the material is less than 1, then that material floats in water. Every material has its own specific gravity, and it usually ranges between 0.1 – 100. We calculate Specific gravity to know the behaviour of the material in water. In simple words, we are comparing the volume of our Testing material either it may be sand, cement, aggregate with the same volume of water at certain temperature. Specific Gravity is the ratio of a Weight of Volume of material (Your testing material) to the same Weight of Volume of water. In this post, I ‘ll clear all of your doubts regarding the specific gravity of cement. Do you know why we calculate the Specific gravity of cement and its significance?. Well most of us know that specific gravity of cement is in between 3.1-3.16 g/cc. Procedure for finding Specific gravity in cement:.Why is kerosene used in the Specific gravity of cement test?.Apparatus Required for Le Chatelier’s Principle:.Specific gravity test /Density of Cement test :.
