No, cement is not heavier then concrete. Since fully-hardened concrete is impervious, any excess water trapped within the mortar or concrete cannot escape once the cement paste has set. For this reason, a hardened bag of cement will always be considerably heavier than a fresh bag. Concrete is a mixture of cement and aggregate, so its mass will change depending on the mass of the aggregate. Steel is more dense than concrete, so the more reinforcing there is in concrete, the more it will weigh.

A similar method is used to pan for gold, since gold has a higher density than most other substances and sinks in a mixture. The specific gravity of cement is around 3. Scientifically, Cement is heavier than Sand! Salt is water soluble, while sand is not. This means the two can be mixed in water and stirred. The salt will dissolve and the sand will not. Sand is heavier than water. They are equivalent. A pail of sand and water, because no matter how full the pail gets, you can always put water in it, making it heavier.
Sand and water both have weight and both have volume. A cup volume of sand weighs more than an equal volume of water.
So the sand pushes the water out of the way and sinks. A cup of wood chips weighs less than an equal volume of water. So the water pushes the wood chips out of the way and they float.
Try it and see. A cup of water has the bigger mass. Because one tiny droplet of water weighs more than one tiny gran of sand. Therefor more water put in a cup would weigh more than more sand put in a cup. It doesn't - wet sand weighs more for the same volume than dry sand. A yard of dry gravel weighs more than a yard of dry sand. Sand sinks in water because sand is more dense than water, not the other way around. A cup of ice weighs more. Sand more dense.
Sand absorbs a higher percentage of the radiation than water does. Water reflects more radiation and allows more radiation to pass through it than sand does. Log in. Units of Measure. Weight and Mass. Study now. See Answer. Best Answer. Sand weighs more then water. Study guides.
