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.

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.
Is gas dense?
Gas is not dense, solids should be dense, liquids are dense, but not as much as solids.
Does more dense or less dense objects settle faster?
More dense.
What are Earths layers from outermost going inward?
From most dense at the core to least dense proceeding outward.
How call you tell if a substance is more or less dense then water?
if it sinks its more dense if it floats its less dense
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).
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.
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.
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
Alternative concrete to dense concrete?
It is called "Foam-crete" or "light weight concrete" either the aggregates used are light weight in themselves or additives are present, that form air spaces (bubbles) with-in the concrete itself, thus reducing the concretes mass. It must be understood that the integrity or strength of the concrete is lost or at least greatly degraded. The product is often used to in-bed the tubes used in "Radiant Heat" as placed over a wooden sub-floor.
Why is it that that concrete is stronger at bottom of column than on top?
when concrete is vibrated while pouring in to the form work, the cement slurry part tends to get drained through voids between aggregates and the richest part of cement slurry is detained at bottom portion of column. this causes a strong, dense, and void free concrete which ensures better compressive strength than the concrete on top portion of column.
What things won't float?
Every rock (minding bedrock) bricks, ships or boats if they get water in them, concrete, cement, televisions, stereos, ....etc. Things more dense that water
