What are the Correct Concrete Mixing Ratios - Ratio Chart

Accurate concrete mixing ratios can be achieved by measuring the dry materials using buckets or even a shovel. 3000 psi concrete mix ratio for 1 cubic yard. 1 : 3 : 3 MIX RATIO. 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)

Construction Specification 14—Pressure Grouting

Grout caps and concrete slabs—Capping and slab concrete are measured to the nearest 0.1 cubic yard by determining the combined weights of cement, aggregates, and water used in concrete mixed and placed as specified, and dividing by a unit weight of 4,000 pounds per cubic yard. Payment for capping concrete is made at the contract unit price

Concrete mixing - by hand, machine or using ready mix

Mixing Concrete . The three main options for mixing concrete are: Mixing by hand - this is probably only suitable where less than about ¼m³ of concrete is required for a job providing that a reasonably fit person is available.; Using a cement mixer - this is generally suitable where between about ¼m³ and 2m³ of concrete is required. It will require continuous mixing of loads and normally
