Cement is usually purchased as a powdery substance that is mixed with sand, aggregate, gravel and water to form concrete. Since the cement itself is usually a powder, it is hard to measure a standard value for it's specific gravity. And since cement is usually not used by itself, knowing it's specific gravity is not particularly useful.

A more useful question is "What is the typical density of concrete?" A rule of thumb answer is that normal cured concrete has a density of about 150 pounds per cubic foot. This includes the weight of the cement, sand, aggregate, and that part of the water that chemcially binds with the cement to form the concrete. Since water weighs about 62.4 pounds per cubic feet, concrete is about 2.4 times as heavy. Thus the specific gravity of concrete is about 2.4. If you took cement and mixed it with water, you would eventually have a hard lump of useless cement and it would also have a specific gravity of between 2 and 2.4.

Ash Grove Cement from the Foreman, AR Facility normally has a specific gravity of 3.15. Depending on the source of the cement, the specific gravity may vary, but typically it will be close to this figure. Knowing the specific gravity of cement is critical when developing a mix design for concrete, because if one does not know the specific gravities of the raw materials, it is not possible to figure the proportions needed to give you the appropriate yield for a cubic yard of concrete.

What is specific gravity of slag cement?

The specific gravity of slag cement typically ranges from 2.8 to 2.9. This value may vary slightly depending on the composition and properties of the slag being used, as well as other factors such as particle size distribution and processing methods.


What is the specific gravity of 50.0ml of urine?

What is the specific gravity heavy fuel?

The specific gravity of heavy fuel oil can vary, but it typically ranges from 0.95 to 1.03. It is important to consult specific fuel oil specifications or test data to determine the precise specific gravity of a particular heavy fuel oil sample.


How do you know a product will float in water using specific gravity of a product using a material safety data sheet?

specific gravity is defined as the ratio of the density of the sample/the density of water. So the specific gravity of water is 1. Anything more dense than water will have a specific gravity above 1 and will sink. Anything less dense than water will have a specific gravity below 1 and will float.


What does Specific gravity urine 1.035 mean?

A specific gravity of 1.035 in urine means that the urine is more concentrated than usual, indicating possible dehydration or certain medical conditions. It suggests that there is a high amount of solutes dissolved in the urine compared to water. Further evaluation may be needed to determine the cause of this high specific gravity.

What will be the effect on specific gravity of cement if some of the sample is lost after weighing?

There is no effect on the specific gravity if some of the sample is removed. The amount of mass will change, but it will still have the same specific gravity. It is basically a density. The specific gravity of 1lb of cement is the same as the specific gravity of 100lbs of cement, you just have more cement.

What is the specific gravity of opc-43 grade cement?

The specific gravity of Ordinary Portland Cement (OPC) 43 grade can vary slightly depending on the manufacturer and specific composition. However, as a general guideline, the specific gravity of OPC-43 grade cement typically ranges from 3.10 to 3.15. Specific gravity is a measure of the density of a substance compared to the density of water. It indicates how heavy a material is relative to an equal volume of water. OPC-43 grade cement generally has a higher specific gravity compared to water, which has a specific gravity of 1.0. It's important to note that specific gravity values can differ slightly based on factors such as cement composition, fineness, and variations in manufacturing processes. For precise information regarding the specific gravity of a particular brand or batch of OPC-43 grade cement, it is recommended to refer to the manufacturer's specifications or contact the manufacturer directly.
