UNIT WEIGHT OF PLAIN CEMENT CONCRETE IS 2400 kG / cubic metre
UNIT WEIGHT OF REINFORCED CEMENT CONCRETE IS 2500 kG / cubic metre .
THESE ARE THE VALUES USED FOR DESIGN OF CONCRETE STRUCTURES.

Most of the volume of a boat is air. So the average density is less than water, so they just displace water. Their weight (downward force) is opposed by an upward force from the water. Boats can be made from very heavy materials such as steel or concrete, just so lomg as there's plenty of air. If you add weight (cargo) the boat sits lower in the water. It displaces more water. "Displacement" is the normal way we refer to the size of the ship. Its in tonnes (of water)., eg 10,000 tonnes. This means it occupies a volume of about 10,000 cubic meters of the sea. The draught might be, say, 5 meters deep, so the area would be around 2,000 square meters. e.g. about 28 x 70m. Most boats do sink eventually. Water gets in. Try floating a plastic box in the sink or bath and add weights to it. If its rectangular (or circular), you can do easy calculations on the volume of water it displaces. Weigh some "cargo" as see it go down an extra x mm.

Volume/weight conversion
Cement
1 cubic yard = 21.6cwt
1 cubic metre = 1.4 tonne

it is generally acceptable to assume concrete density to be 2400kg/m3. One component you forgot is sand. The weight is significant.

you'd have to know the weights or densities of the balast and cement.

depends on if it is wet or dry
