Answers:
you ask to teck. a question for me to answer. A good rule of thumb,
2 parts cement, 3 parts sand and 5 parts gravel, the dryer you can mix it the better cement you will have. stay off it for at least 3 days and keep it watered down, so it will cure slow. If it flat work, go heavy of re bar. Impossible to get too much iron.
