How to Make Concrete
Plan your concrete project carefully. There is a set sequence of steps you must take to be successful, and following them will save you a lot of problems later on.

1.2. -------------------------------------------------
Purchase or gather the raw materials for your concrete. You will need Portland type I or II cement, masonry or builder's sand or other cleansand, and if you want, as a filler, gravel or crushed limestone. The Portland cement usually comes in one cubic foot bags, weighing in at about 96 pounds each, so you may need help handling them, as wellas a truck to haul it.

Build amixing box, or get a good, sturdy wheel barrow to mix the materials in. If it is a large project, rent a concrete mixer to do the hardest part of the work for you. We have mixed as much as 6 or 8 cubicfeet with a mason's hoe and shovel, in a large plastic tub, so not having the best equipment shouldn't stop you from trying it.

Allow yourself time to complete the whole process when you begin. If the concrete is a large "finished" slab,start early in the morning and gather all the help you can.

Build the form you are placing the concrete in, brace it off securely, level and plumb it up, and then carefully measure the dimensions to determine the volume in cubic feet.This is done by multiplying width X length X height in feet. An example would be 5 ft. X 2 ft. X .5 ft. (6 inches)= 5 cubic feet.
