Proportions are an endless subject of debate but the formula of 1 part cement, 2 parts sand and 3 parts gravel by volume is a good starting point. Mix the dry ingredients first and then slowly add water. You want "workable" concrete. As you add water the concrete will go from unworkable to workable to sloppy.
