to figure it out you just need to take the weight of the cinderblock and minus the weight of the same amount of water. to find that get a tub of water filled to the brim and put it in some thing that can catch the water that spills out when you put the cinderblock in the tub. then all you have to do is weigh the water and deduct that from the weight of the cinderblock. then the weight remaining is the weight unerwater of the cinderblock

∙ 14y agoIt depends on your mix -- those darned college kids keep making canoes out of concrete that floats (http://content.asce.org/conferences/nccc2010/) but they're using admixtures that the normal world can only dream of.
Normal concrete is about 145lbs per cubic foot, and normal lightweight concrete would be about 2/3 of that.
Water is a nominal 62lbs per cubic foot. so you're looking at around 80lbs/cubic foot of negative buoyancy with normal mix.

How much does a concrete cinder block weigh?

What does an 8 x 10 x 16 concrete block weigh Is there a difference between a concrete block a concrete cinder block?
It weighs 59 lbs. There is a difference between a "real" cinder block and a concrete block. A cinder block uses cinders--ash from the burning of coal--as its aggregate. Concrete blocks are made from concrete. Concrete block is far stronger than is cinder block, and some jurisdictions prohibit the use of cinder block. The only justification for cinder block is that it weighs less than concrete block, which is important if the ground you're building on isn't strong enough to support a heavy structure. This justification has gone away, because now you can buy concrete block made from expanded-shale aggregate that's as light as cinder block and as strong as standard-weight concrete masonry.

How heavy would a cinder block be on Ceres?
Cinder blocks come in different sizes and weights, so in order to answer this question let's assume that the cinder block is a "light weight" version, which weighs about 28lbs here on Earth. Ceres, which is a dwarf planet (or "planetoid"), has a surface gravity of 0.27 m/s^2. Thus, a cinder block would weigh 0.7706lbs on Ceres.
