Concrete Blend

If concrete is needed for a project and using a truck full of premixed concrete is not an option, then it will have to be blended on site…so what does that entail? Well the good news is that at Centenary Landscaping Supplies, we have Concrete Blend already mixed in our Darra yard where the sand and drainage gravels are blended in the correct ratios ready for you to use …

Some important points to note: As with all materials, if you need a hand in working out the volume required, then give us a call at the office remembering that you can buy the Concrete Blend in any amount you like …from as small as a shovel full, to a trailer or ute load or even a full truck load!

There are three blends available, two with a 10mm stone and one with a 20mm stone and all are more than capable of performing most tasks around the home and garden be it a concrete slab for a garden shed, footings for a retaining wall, garden edging, etc. The larger stone will make a slightly stronger mix but is not as versatile as the 10mm and for that reason about 90% of all the blend we sell is mixed with the 10mm stone.

If working out the volume of concrete blend required for a slab or path always allow for a little bit of shrinkage, as when water is added and all the voids are filled the total volume of the mix is slightly less.  For example, if the exact mathematical volume needed is 2.3m3, then closer to 2.5m3 would be needed.

As a general rule of thumb, you will need 16 bags of cement to go with every cubic metre of concrete blend.  This equates to roughly 16 mixes in a 2.2 cubic foot mixer. which would be roughly 16-20 barrow loads! Now you know what you’re in for!
