Where a more structural concrete is required you may need to add neat cement to the premixed bag.

Volume of concrete per 20kg bag.

For jobs where a stronger rated concrete is needed youmay consider our high strength concrete mix for your concreting purposes. This series of concrete calculators has been developed to help you plan your project. Preparation formwork made from 25mm thick timber is commonly used to mould the concrete. Pre mix concrete bag calculator calculated at 2160 kg per 1m allow extra for waste cubic metres 20 kg bags 25 kg bags 30 kg bags 40 kg bags per bag.

One 20kg bag will cover an area of 1 1m2 to a depth of approximately 10mm. 20kg bags can be bought individually or as a pallet of 70. Yields are approximate and will vary based upon placement methods equipment utilized and do not include allowance for uneven subgrade waste etc. We love to stir fry and mix things up here with all sorts of internet businesses.

The addition of 1 6 1 8 litres of water to a 20kg bag of hi strength 36 will produce around 11 5 litres of concrete. The more cement the more costly of course so don t over do it. You can calculate how much concrete cement sand mortar or render you will need. All calculations are rounded up to the next highest whole bag.

1 cement 2 5 sand 4 aggregate is ok for fence posts. 13bags of cement per cubic metre. Or 108 x 20kg bags equates to one cubic metre of mixed concrete. The calculator will indicate the estimated number of 25 kg or 30 kg bags of quikrete concrete mix needed to build a 3 4 or 6 slab with a typical waste factor.
