Does mixing cement weigh the same as dried concrete?

no, it will weigh heavier because it will dry into cement when mixed with water and the weight of water will add to the weight of the concrete.

A cubic yard of concrete should weigh about 2 tons (4000 lbs).

The weight of one cubic metre of gravel concrete is 23,550 Newtons. Cement concrete weighs less: 23,240 Newtons.

P.S.- how did you find this out? Do you weigh 80 lb. bags of cement for fun? rofl ^_^

This can vary do to the mixture of sand, stone, cement... but an approximate average would be 3000 lbs

how much does a gallon of concrete weigh

One cubic metre of concrete weighs 2.5 Tonnes. Typically, 1m3 of concrete is made up of 350Kg of cement, 700Kg of sand, 1,200Kg of chippings and 150 Litres of water. http://www.planete-tp.com/en/article.php3?id_article=221

How much does a 24"x24"x2" concrete paver weigh

would a scale that is used to weigh food be the best tool to weigh concrete blocks

That depends on how much you have purchased.

The specific gravity of limestone concrete is 2.37. Therefore 5 gallons of concrete would weigh 94.8 pounds.

Thisquestion needs clarifying. The question should be 'how much does a CUBIC metre of concrete weigh'. A square metre of concrete would have to have a thickness to make volume.

Concrete is made of a mixture of cement, aggregate (small stones), fine aggregate (sand), water and other chemical additives. When mixed the wet concrete will remain so for Most people assume that set concrete has no water in it, this is not so, as the water content helps bond the aggregates and cement, this process is known as Hydration. Concrete with no water in it would crumble to dust. Adding more water to the mix will make a concrete that is easier to work, while less water will produce a stronger, more durable concrete. After initial setting of the concrete, a slow amount of water loss is expected due to the concrete drying, it can take anything up to a year for water to stop evaporating slowly out of the concrete. So for this reason the answer to your question is yes, dry, set concrete will weigh less than wet concrete, but for anything up to a year it will keep getting lighter, due to waterloss.

It weighs around 1500 kg/cum. and solid concrete blocks weigh around 1800 kg/cum minimum.

How much does a cubic metre of concrete weigh? One cubic metre of concrete weighs around 2.4 tonnes. That equates to about 20 wheelbarrow loads per m3!

For a regular mix of concrete, the weight of one cubic yard is around 4,000 pounds. A mixture of lightweight concrete will weigh about 3,000 pounds per cubic yard.

5 gallons of cement would weight 5 * the weight of 1 gallon

60 kg = 132 pounds, whether of feathers or cement.

A typical concrete paver weighs between 8 and 10 pounds. A single brick will usually weigh between 3 and 5 pounds.

because there's less water in it.

Concrete is a variable material. On average it's about 0.139 ounces.

Where are 12 inch concrete blocks applied?

half a kilo approximately

It would weigh the same unless you got the concrete and stone from another planet.

The weight of concrete depends on the materials used in the aggregate and the method used to prepare it. 45 gallons of a dense concrete mixture can weigh up to 1,500 pounds, and special lightweight aggregate prepared using foaming techniques may weigh as little as 200 pounds.
