What is the specific density of concrete?
150 pounds per cubic foot
“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.”
What should be the range of specific gravity of a good cement?
A good cement should have the Specific gravity of 3.1-3.6 g/cc.
What is specific gravity of PPC cement?
The specific gravity of OPC used in the study was about 3.06 gr/cm3, whereas for the PPC it was around 3.08 gr/cm3.
How much does 1.5 cubic meter of concrete weigh?
A typical concrete mix weighs 150 lbs per cubic foot, 4,050 lbs per cubic yard, or 2,400 kg per cubic meter.
Is 455 a grade of cement?
The initial and final setting times and compressive strength requirements are same as that for 33 grade ordinary Portland cement. Uses: This cement can be used in all places where OPC is used.
Is 2720 specific gravity?
This standard ( Part III ) deals with the method of test for determination of specific gravity of soils which finds application in finding out the degree of saturation and unit weight of moist soils. The unit weights are needed in pressure, settlement and stability problems in soil engineering.
What is the specific gravity of brick?
| Product | Specific Gravity – SG – |
|---|---|
| Brick, common red | 1.75 |
| Brick, fire clay (firebrick) | 2.4 |
| Brick, hard | 2.0 |
| Brickwork, in cement | 1.8 |
How to calculate specific gravity of cement?
Procedure for finding Specific gravity in cement:- The Lechatlier flask should be free from moisture content, that mean flask is thoroughly dried. Now, weigh the empty flask and note it as W1. Take 50gm of cement and add it in Flask. Now pour kerosene in the sample up to the neck of the bottle. Empty the flask and fill the bottle with kerosene up to the tip of the bottle and record the weight as W4.
Why specific gravity of cement is important?
The specific gravity of cement is important because it is one of the factor which determines the density of the cement. As we know that, the cement may contain lots of moisture content if it is exposed to various conditions and humidity. We all know that water cement ratio is an important factor of cement paste.
What is the value of the specific gravity of cement?
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.
Why is the specific gravity of cement tested?
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.
