The portland cement have a specific gravity of value around 3.15. When it comes to portland pozzolan cements and portland blast furnace cements the value will come near to 2.90 […] 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 water.
A concrete mix is to be designed for use in a 250 mm (10 inch) thick JPCP pavement. The desired properties are: Slump = 25 mm (1.0 inch) Average 28-day flexural strength of at least 4.5 MPa (650 psi); Coarse aggregate: nominal maximum size = 37.5 mm (1.5 inch), dry-rodded weight = 1600 kg/m 3 (100 lb/ft 3), specific gravity = 2.68, moisture content = 1.0 percent, absorption = 0.5 percent

Specific gravity and Water Absorption Test of Aggregate major important test to be performed on aggregate. These two parameters or property of aggregate play an important role in the mix design of concrete.As we know that aggregate occupies 70 to 80% volume of concrete, it testing becomes essential before use.
Reference(s): Byrne et al. (1998) Gomez (2009) Lazarte et al. (2015) Method Summary The specific gravity test is conducted on grout prior to and during grouting as a quality control measure and is used to confirm the water content (i.e., water-cement ratio) of the grout.

Apr 06, 2018· Specific gravity of cement is tested in order to know the various atmospheric effects on the moisture content of a cement. Generally nominal Mix design is based on the value of specific gravity of cement as 3.15. The value will change over time if the cement is exposed to various weather conditions. So it is essential to determine the specific ...
Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity for liquids is nearly always measured with respect to water at its densest (at 4 °C or 39.2 °F); for gases, air at room temperature (20 °C or 68 °F) is the reference. The term "relative density" is often preferred in ...
For example, to determine the specific gravity of cement will consider water as reference substance. In simple words, the specific gravity determines whether the material will sink or float in water. Every material has its own specific gravity and the value normally varies from 0.1 to 100.
The specific gravity of all other materials are compared to water as a fraction heavier or fraction lighter density, no matter how small or large the fraction is. For example, ammonium nitrate has a specific gravity (sg) of 0.73 while dry ammonium sulphate has a sg of 1.13 (1130 kilograms/cubic meter).

May 13, 2020· Specific gravity, ratio of the density of a substance to that of a standard substance. Solids and liquids are often compared with water at 4 C, which has a density of 1.0 kg per liter. Gases are often compared with dry air, having a density of 1.29 grams per liter (1.29 ounces per cubic foot) under standard conditions.
Specific requirements of ordinary Portland cement for manufacture of railway sleepers to be designated as 53-S grade are given in 5.2, Table 3 and 10.1. To differentiate it with normal grade, '53-S grade' shall be marked on the bags/packages for such cement in place of '53 grade'.
Specific Gravity of cement is the ratio of the density or mass of cement to the density or mass of a reference substance. But in both of the state's density or mass, the volume should be same. If the volume does not remain same the specific gravity has no existence then.
Fineness Test of Cement. PROCEDURE OF FINENESS TEST OF CEMENT: Collect a sample of cement and rub with your hands. The Fineness test sample should be free of lumps. Take 100 gm of cement sample and note its weight as W1. Drop 100 gm of cement .
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}})..

Aug 03, 2018· Now we start calculation for find Cement, Sand and Aggregate quality in 1 cubic meter concrete. CALCULATION FOR CEMENT QUANTITY; Cement= (1/5.5) x 1.54 = 0.28 m 3 ∴ 1 is a part of cement, 5.5 is sum of ratio Density of Cement is 1440/m 3 = 0.28 x 1440 = 403.2 kg We know each bag of cement is 50 kg
If the specific gravity of cement is greater than 3.19 then, the cement is either not minced finely as per the industry standard or it has more moisture content which will affect the mix and bonding. This is why you find lots of chunks while mixing old stock cement for concrete.
Because the density of water is 1 g/cm3, it is the most widely used reference substance for determining the specific gravities of solids and liquids. The density of any substance in grams-per-cubic-centimeter is nearly the same numerically as its specific gravity relative to water.
Hiiiiii, The specific gravity of cement is taken as 3.15. This means the solid particles of cement themselves have a density of 3150 kg/m3 which is equal to 3.15 grms/ml or 3.15 g/cm3 or 3.15 kg/litre. 3150 kg/m3 = 3.15 grms/ml = 3.15 g/cm3 = 3.15...
