Normal concrete has a density around 2400 kg/cubic meter or 4048 lb/cubic yard. There are many different kinds of concrete, many of which are much lighter. Cement is the liquid (or paste like) form, and tends to be much heavier than when it has cured into concrete. "Cement" is not concrete, but can be used to make concrete by mixing with sand, stone and water. The density of cement is about 3120kg/m3.
What else can I help you with?
Is the femur as hard as concrete?
No, the femur is not as hard as concrete. The femur is a bone in the human body that is strong and dense, but it is not as hard or rigid as concrete, which is a non-living material typically used in construction.
Can Radon gas pass through a concrete slab?
Yes, radon gas can pass through concrete slabs. While concrete is a dense material, it is not completely impervious to radon gas. Proper sealing and mitigation measures should be employed to reduce radon infiltration through concrete slabs.
How do the densities of pure substances differ from the densities of mixtures?
There's no correlation between the composition of a substance and its density. Pure ethanol is less dense than potato-leek soup, but pure mercury is more dense. Potato-leek soup is less dense than pure mercury, but concrete is more dense.
What are Earths layers from outermost going inward?
From most dense at the core to least dense proceeding outward.
Where cool dense water sinks it become more dense?
In the Mediterranean Sea the cool dense water sinks under less dense water which is called density current.
Does concrete absorb sound?
No, concrete does not absorb sound as it very dense.
How do reduce density of concrete?
Add ballast that is less dense than the gravel/sand in the concrete such as LECA (Light Expanded Clay Aggregate).
Is the femur as hard as concrete?
No, the femur is not as hard as concrete. The femur is a bone in the human body that is strong and dense, but it is not as hard or rigid as concrete, which is a non-living material typically used in construction.
Why might a glass survive a fall on the carpet but not on a concrete floor?
The carpet is made of material that spreads the shock across the surface area of a greater distance than concrete. Concrete is more dense than carpet making it susceptible.
How much does 100cm x 40 cm x 3 cm of concrete weigh?
It depends on the mixture of concrete. some concretes can float and some are extremely dense. The density of a concrete is dependent on the material it is made from, typically the aggregate. So without a known density for the concrete this cannot be answered.
Can Radon gas pass through a concrete slab?
Yes, radon gas can pass through concrete slabs. While concrete is a dense material, it is not completely impervious to radon gas. Proper sealing and mitigation measures should be employed to reduce radon infiltration through concrete slabs.
Why does concrete float?
Concrete does not float naturally in water; it is denser than water. However, when concrete objects such as boats or platforms float on water, it is typically due to buoyancy provided by a hollow structure or trapped air pockets within the concrete. This buoyant force can make the overall concrete object less dense than water, causing it to float.
How can one effectively block gamma radiation?
Lead and concrete are effective materials for blocking gamma radiation. Lead is dense and absorbs gamma rays, while concrete provides a barrier that can block the radiation. Using a combination of lead and concrete shielding can effectively block gamma radiation.
Why do objects float better in salt water then in normal water?
Because saltwater has a higher density. It's like if you were to try to float a rock in water and then in wet concrete, it will stay afloat on the concrete because it is more dense.
Does sound travel in concrete?
Yes, sound can travel through concrete. However, concrete is a dense material that absorbs and reflects sound waves, which can help reduce noise transmission compared to materials like wood or drywall. The thickness and composition of the concrete will affect how well sound travels through it.
What is the noun for dense?
There is no abstract noun form for the adjective 'dense'.The noun form of the adjective 'dense' is denseness, a concrete noun as a word for the physical property of something.A related noun 'density' is also a concrete noun.An abstract noun is a word for something that can't be experienced by any of the five physical senses; something that can't be seen, heard, smelled, tasted, or touched.The noun 'denseness' is sometimes used as an informalterm (slang) for 'stupidity', a word for a concept.
Why if you drop a gold ball on pavement does not bounce highly?
because gold is heavy? and the concrete is too solid/dense to harness the kinetic energy from the fall of the gold ball because when it meets with the concrete the energy is turned into potential energy
