How much weight can a concrete floor withstand?

How much does concrete weigh underwater?

This varies but concrete (only – no rebar) density is ~150 lb/cubic foot; water is ~ 62 lb/cubic foot. This makes the concrete “weigh” about 60\% submerged making the total “weight” about 60 tons underwater. A good demonstration as to why concrete makes poor ballast for sailboats.
