I have to build a cement boat that will hold as much weight as possible. It must be made completely out of cement, no styrofoam, wood, or anything that would provide buoyancy. It can be 1 cubic foot maximum. How would I go about doing this?? Can you add aggregate to the cement? Can you use chicken wire or some other metal wire material? When concrete (aggregate + cement) is used for structural purposes it is usually reinforced with bar material of some sort. And cement is usually mixed with some type of aggregate. Is this a university competition? Is there a website with the full rules? --Mac |
