Mass of the same volume of water, Ww = (W1 + Ws) – W2 G = Mass of soil / Mass of equal volume of water G = Mass of soil / Mass of equal volume of water Calculation Of Specific Gravity Of Soil Sample The specific gravity of soil can be calculated by using the following formula, Read More: 7 Brick Test to Decide Quality of Bricks Specific Gravity of Soil Formula

Find out the mass of the dry soil in the evaporating dish (Ws).

Transfer evaporating dish into the oven to dry to a constant weight.

Clean the bottle such that no soil particles are left on the side.

Empty Soil and water in an evaporating dish.

Just as a precaution, check the temperature of the soil and water in the flask to see if it’s T1± 1 ✬ or not.

Find out the combined weight of the bottle + Soil + Water as (W2).

Also, clean the top and side of the bottle and remove any excess water.

Now fill the distilled water into the bottle until the bottom of the meniscus touches the 500 ml mark.

(This temperature of the water is at room temperature.) Bring the temperature of the soil-water mixture in the Bottle down to room temperature, i.e T1 ✬ seen in Step 4.If this entrapped air is not removed completely it can cause a result error. This is the most important step for testing.The second option is to vacuum by a vacuum pump or aspirator until all of the entrapped air is out.(Don’t use high flame otherwise, the soil may boil over.) Accompany the boiling with continuous agitation of the flask. Gently boiling the specific gravity bottle containing the soil-water mixture for about 15 to 20 minutes.Remove excess air from the soil-water mixture.Add distilled water to the gravity bottle containing the soil (or the soil paste) to make it about two-thirds full.Now, Fill this soil (if granular) or the soil paste (if cohesive) into the volumetric specific gravity bottle.Keep it soaked for about 1 hour at least in the evaporating dish. In the case of cohesive soil, add water (de-aired and distilled) to the soil and mix it into the form of a smooth paste.Fill approx 100gm of dry soil into an evaporating dish.Insert the thermometer into the bottle with the water and determine the temperature of the water T = T1 ✬.Determine the weight of the bottle and the water filled to the 500 ml mark (W1).Carefully fill the bottles with de-aired, distilled water up to the 500 ml mark.Clean the specific gravity bottle well and dry it.The equipment for this experiment is shown in Fig. Thermometer graduated in O.soC division scale.Specific Gravity Test of Soil IS Code: IS (1980) Apparatus Read More: Water Content of Soil Test – Procedure, Result & Report Determination of Specific Gravity Test of Soil

The Specific gravity of soil generally ranges from 2.60 to 2.90. Organic matter and porous particles may have specific gravity values below 2.0 and Soil which has heavy substances or particles may have values above 3.0. General Specific Gravity of Soil Range for Various Soils

This method of determining the specific gravity of soil given here is applicable for soils composed of particles smaller than 4.75 mm (No.4 U.S. The general values for specific gravity for different soils are given in Table -1. Gs = Unit weight (or density) of soil sample only / Unit weight (or density) or water 10×10 Room Construction Cost Excel Sheet.Construction Material Testing Menu Toggle.30×40 House Plans | 1200 sq ft House Plan.20*50 House Plan | 1000 sq ft House Plan.
