A concrete calculator is a very interesting and handy thing to have. I didn't know so much went into pouring concrete. I made a concrete slab in a back yard garden one time. I didn't do to bad. If I would have known about a concrete calculator I would have had just enough concrete. It was a very time consuming job. It was a good learning experience. A lot of fun as well.
