The basic types available to the amateur constructor are

Sugar (fuel) with potassium nitrate, KNO3 or Sodium nitrate NaNO3 (Oxidizer) also known as candy propellant. The propellant can be improved by using specific sugars ie dextrose. The components can be dry or wet mixed or melted together, with care.
See for a very comprehensive primer on this propellant and a very good education on rocketry.

Zinc sulphur This is a rocket propellant that has fallen from favour as it is less predictable with a isp similar to candy. A manual called Micrograin by BJ Humphries may be available via Amazon or Abe books

For the advanced experimenter ammonium perchlorate, aluminium powder set in a solid rubber binder is the most powerful propellant the amateur can work with. The solid fuel boosters on the space shuttle use this mix. See for hobbyists working with this propellant combination.
A very good book is How to make Amateur Rockets
Read this First! This well help you figure it out!
