S c = specific gravity of cement. W = Mass of water per cubic metre of concrete, kg. C = mass of cement per cubic metre of concrete, kg. p = ratio of fine aggregate to total aggregate by absolute volume. f a, C a = total masses of fine and coarse aggregates, per cubic metre of concrete, respectively, kg, and
Specific Gravity is the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. Water, at a temperature of °F (23°C) has a specific gravity of 1. Specific Gravity is important for several reasons. Some deleterious particles are lighter than the good aggregates.
Specific gravity, water absorption and gradation of sand (FM) test were carried out as per IS 2386 (part I and Part III) 1963. Physical test for specific gravity, water absorption, bulk density were carried out for coarse aggregate as per IS 2386 (I, II IV) 1963. Table 3 .
Enter the specific gravity for the sand. Enter the total moisture content (TMC) and absorption factor for your fine aggregate, if desired. Enter "0" if you do not wish to factor the moisture contents. Coarse Aggregate #1 is required.

The code criteria to be satisfied during a mix design are the maximum water /cement ratio, maximum size of aggregate and air contents within specified limits ... SSD specific gravity of fine and coarse aggregate = ... Water/Cement ratio of the concrete mix will depend upon the target strength of concrete mix. The following table show the ...
Sep 10, 2017· Specific gravity test /Density of Cement test : As per Le Chatelier's Principle, Specific gravity of cement is determined by Le Chatelier's Flask method. And the IS code for Specific gravity test is IS 2720 Part 3. Apparatus Required for Le Chatelier's Principle:1. Cement 2. Kerosene 3. Specific Gravity Bottle capacity of 250 ml with stopper. 4.
The specific gravity (SG) of cement was determined according to the British Standard (BS 1377: Part 2) using the small pycnometer method. The fineness of the cement was determined by conducting the Blaine surface area test according to ASTM C 20494a and shown in Table 2 .
Simply stated, it is the unit weight of a dry material (gdry) divided by the unit weight of water (gwater). Gs = gdry / gwater or gdry = Gs x gwater. To determine the unit weight of a substance like cement, multiply the specific gravity of the cement by the unit weight of water.

watercement ratio, specified minimum cement factor, percent air, and the specific gravity (Bulk, Saturated Surface Dry Basis) of each aggregate. The specific gravity is determined by tests conducted on samples obtained from project stockpiles.
Fig. 4. Plot of Density of Concrete vs. CementWater Ratio and Specific Gravity. RECOMMENDATION. The use of suitable specific gravity along with cementwater ratio in concrete mix can determine and evaluate the expected weight, quality and strength of concrete mix. By this concept, quality of concrete mix is related to its specific gravity. REFERENCES
