Specific gravity is the ratio of the weight of a cubic foot of a material to the weight of a cubic foot of water, which is 62.4 pcf. Therefore, the specific gravity of a typical concrete mix is 145/62.4 or 2.32. This table is a data information resource for the specific gravity of …
Bureau of Reclamation, US Department of the Interior. "Typically, concrete has a density of 150 pounds per cubic foot, which means that a block of concrete that is one foot wide, one foot long, and one foot high would weigh 150 pounds. Water has the density of only 62.4 pounds per cubic foot." 2400 kg/m 3.
D. Specific gravity Test : The Specific Gravity test was conducted as per IS: 2386 (Part III) – 1963. The Specific gravity of coarse aggregate was determined as 2.309. It was 13% reduce from standard value 2.67 which is in the range from 2.5 to 3.0. The Specific gravity of fine aggregate was also accurate.

In this definition, the volume is that contain both the sand and the voids between sand particles. The approximate bulk density of sand that is commonly used in normal-weight concrete is between 1520-1680 kg/m3 (95-105 lb/ft3)  Here, Standard test method for determining the bulk density of sand is given in ASTM C 29 (AASHTO T 19).
Specific gravity of concrete: Lightweight aggregate concrete: 2100 kg/m 3. Ordinary concrete: 2300-2450 kg/m 3 Heavy concrete: more than 2500 kg/m 3. If you have any question or any need about construction materials, such as concrete or silica fume, please contact us by E-mail ...
Bulk specific gravity of concrete materials Portland Cement 3.15 Pozzolan 2.2 to 2.8 Natural Aggregates 2.4 to 2.9 Water 1.0 Bulk specific gravity applies to porous materials. For non-porous materials the specific gravity and bulk specific gravity are the same. BULK SPECIFIC GRAVITY SATURATED SURFACE DRY (Gs(ssd))- The bulk
I would like to point out that there are conceptual differences between density, specific weight and specific gravity. Follow the link if you want to learn more about these differences. With that said, this page will provide you the reinforced concrete density in kg/m³ (SI unit), g/cm³, g/ml, kg/l, lb/ft³. Density of Reinforced Concrete
Generally, the specific gravity of cement ranges from 3.1 to 3.16 g/cc. From this, we can say that the specific gravity of cement is more than the specific gravity of water that is 1. It means cement will sink in water if we put it on the water. Also, we can say that cement is heavier than water.

The Le Chatelier specific gravity flask is also utilized to determine the specific gravity of dust, sand, and other fine materials. This specific gravity of cement is an essential parameter in concrete mix design material quantity calculations. This specific gravity of portland cement is about 3.15 and can be measured using ASTM C188.
Specific Gravity of Cement is nothing but the ratio between the volume of cement to the volume of the same quantity of water. Usually, the value lies between 3.10 – 3.16 g/cc. Some types of cement such as PPC, Portland Blast furnace slag will have the value near 2.90. In simple, Cement is 3.10 times heavier than the water.
As we know that the specific gravity of cement ranges from 3.10 to 3.25 Mg/m 3, it can be concluded that it is 3.10 to 3.25 times heavier than the same volume of water and it will sink in water because the specific gravity is greater than 1. Nominal concrete mix is prepared with the cement of specific gravity 3.15.
Answer (1 of 5): -The specific gravity of any substance is the resultant of diving its density over the density of water, of course at the same conditions of temperature and pressure, say ambient conditions, the density of water is 62.4 lb/ft^3 or 1 gram/cm^3 …
Significance Of Specific gravity Of Cement: As we said earlier, cement may contain excessive moisture content if it is exposed to the various weather conditions and we all know that w/c ratio is a big factor which determines the concrete strength.
Specific Gravity of Concrete. Generally, the specific gravity of cement ranges from 3.1 to 3.16 g/cc. From this we can say that the specific gravity of cement is more than the specific gravity of water that is 1. It means cement will sink in water if we put on the water. Specific Gravity of Cement Procedure
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).
enter the specific gravity of the course aggregate and the fine aggregate. Volume of coarse aggregate per unit volume of concrete Nominal maximum size of aggregate, in (mm) Volume of oven-dry-rodded coarse aggregate per unit volume of concrete for different fineness moduli of fine aggregate 2.40 2.60 2.80 3.00 3/8 (9.5) 0.5 0.48 0.46 0.44
Absolute specific gravity (ASG) refers to the solid material excluding the pores, and bulk specific gravity (BSG), sometimes called apparent specific gravity, includes the volume of the pores. For the purpose of mixture proportioning, it is important to know the space occupied by the aggregate particles, including the pores within the particles.
what is specific gravity of concrete? concrete; asked Jul 28, 2015 in Concrete Technology by mfby2k . 1 Answer. 0 votes . The ratio of the mass of a solid or liquid to the mass of an equal volume of water, specific gravity of cement is …
Specific gravity is an important property of cement being related to its density and viscosity. It is one of the factor to determine density of cement. If the specific gravity of cement is more than 3.19 then it has more moisture content, which will affect the mix and bonding.
specific gravity of 2.65 was used. Zone 2 was the grading of the aggregate. C. Coarse Aggregate: Aggregates greater than 4.75mm are considered as Coarse aggregate. Crusted coarse aggregate of 20mm downsize were used with fineness modulus of 4.32 and a specific gravity of 2.84. D. Steel Slag: In this experiment the steel slag collection is
2) Fill the specific gravity bottle with cement sample at least half of the bottle and weigh with stopper (W2). 3) Fill the specific gravity bottle containing the cement, with kerosene (free of water) placing the stopper and weigh it (W3). 4) While doing the above do not allow any air bubbles to remain in the specific gravity bottle.
Specific gravity influences the concrete mix in the following ways: 1. Specific Gravity of Aggregates Affects Concrete Volume. Specific gravity of aggregates that are planned to be used in concrete mix design is determined to study the absolute volume of aggregates that will occupy in the concrete mixture.
