I have a root cellar which looks similar to the one in this link.

The floor is simply the dirt ground. I want to use the cellar to store various items/equipment and therefore want to put in a floor. I thought of putting in a cement floor, but was told that that would not be a one man job due to having to mix and lay down the cement all in one day. Is this true or is it possible to lay a cement floor by working in sections over time? Are there alternative materials I could use that would work aesthetically well with this type of structure? Thanks.
