mix the dry materials in a ratio of 3 parts gravel to 2 parts sand to 1.5 parts cement in a bucket. this is sometimes listed as 3 to 2 to 1. a higher amount of cement will create a stronger material.
mix concrete for repairs pour enough dry concrete mix into a 5-gallon bucket to repair any cracks and patch damaged areas. sand mix or concrete resurfacer, which do not contain gravel, may be used if the area to be repaired is not large or deep.
the ideal concrete mix to use for constructing a driveway should have at least a 4,000 psi compressive strength, a water-cement ratio of 0.50, aggregates no larger than 1-inch in size, and a slump thickness of 4 to 5 inches. in colder climates, the mixture should have an air-entrainment value of 6%.

gravel and sand compacts best with a drum roller or a vibrating plate compactor. “we use an 8-ton rubber-wheeled drum roller,” says lloyd, “and compact to 98%--both the subgrade and the subbase. when we’re done it’s almost like concrete. when the laser screed or ready-mix trucks drive across it they won’t even leave tracks.
slabjacking to lift sunken concrete. if your driveway slab is sinking in spots, the problem is most likely due to a poorly compacted subgrade or soil erosion. slabs can be raised back to their original position by pumping a mixture of sand, cement, fly ash, and other additives beneath the slab—a process called slabjacking.
the best mix for concrete driveways is: 1 part cement. three parts sand. three parts aggregate will produce a concrete mix of approximately 3000 psi. by using these materials, they follow these steps: mix water with the cement, sand, and stone, which will form a paste that will bind the substances together until the mix hardens. alter the materials, as the strength properties of the
one of the best concrete mix ratios is 1 part cement, 3 parts sand, and 3 parts aggregate, this will produce approximately a 3000 psi concrete mix. the strength of this mix ratio is good for most concrete slabs, footings, steps, and foundation walls.
to make 1 cubic metre of 15 mpa concrete you will need to mix 5 1/2 bags of cement with 0,75 cubic metres of sand and 0,75 cubic metres of stone. 25 mpa this is a medium strength concrete and is suitable for reinforced foundations, light-duty house floors, patio slabs, footpaths, steps, driveways and garage floors.

this gives you a basic 3000 psi concrete mix ratio of: 1 part cement 3.25 parts stone 2.93 parts sand; rounded off it's basically a 1 : 3 : 3 mix ratio. if i break the weights down per yard of concrete it comes to: 1. cement = 510.75 pounds. 2. stone = 1658.75 pounds. 3. sand = 1496.25 pounds
strength follows the water-to-cement ratio as surely as day follows night. a w/c ratio of 0.045 and 5-1/2 sack content with 900-kg (2000-lb) of large aggregate with welded wire reinforcement is a good standby mix design for an interior slab-on-grade. the strength will fall around 30 n/mm 2 (4500 psi).
