What is "clean fill" dirt?

We recently dug out an old garden patch that was up against our house. Just wondering what the best type of fill to use to bring the soil level back up above the foundation. We have some mixed 3/4 minus, sand and soil left over from a patio project and wonder if that would do. We would of, course, grade it away from the house.
