Concrete Mixing Ratios

To produce a 3000 psi cubic yard of concrete (27 cubic feet) the concrete mixture ratio is: 517 pounds of cement or (234kg) 1560 pounds of sand or (707kg) 1600 pounds of stone or (725kg) 32 - 34 gallons of water or (132L) This mixing ratio will give you a concrete mix that is strong, durable, and good for most concrete projects.
