Description
Cement Australia Rapid Set Concrete is a dry concrete mix, made in Australia, formulated to harden rapidly so a post job can be finished sooner than with a standard concrete mix.
Cement Australia lists it for fixing fence and non-load bearing pergola posts, clothes hoists and many other non-structural uses. It is not designed for use in any structural application.
It is not mixed in a barrow. Water goes into the hole first, then the dry mix is poured in and tamped around the post. Supports may be removed after 1 hour, depending on the ambient temperature.

How to Apply
- Position and support the post: place the post or pole in the hole and support it so it cannot fall over.
- Pour water into the hole: start with 2.0 litres per 20kg bag.
- Add half the bag: pour half the bag evenly around the post without delay, then tamp it with a rod to remove air pockets.
- Add the rest and tamp again: add small amounts of water only if needed so the mix is completely moistened. If the hole needs more concrete, repeat straight away with another bag.
- Remove supports after 1 hour: depending on the temperature. Check the post is stable before removing the supports.
Important Notes
- Wet cement is alkaline and can burn skin and eyes. Wear gloves, eye protection and a P2 mask, avoid breathing dust when opening or mixing, and wash it off skin promptly. See the Safe Work Australia guidance on cement and silica dust.
- Cement, sand and aggregate contain crystalline silica. Keep the material damp where you can, avoid breathing the dust, and wear a P2 mask if it is dry and dusty.
- Not designed for use in any structural application.
- Not recommended for use below 10°C.
- Do not add extra cement, sand, other aggregates or admixtures to the mix.
- Store dry and use within the shelf life stated on the bag.
