Quick Set High Strength Concrete

Easy Mix Quick Set High Strength Concrete is a premixed, 32MPa bagged product containing accurately weighed Portland cement, graded coarse and fine aggregates and quality admixtures. It also incorporates a non-chloride accelerator which ensures a far more rapid setting time when compared with standard concrete.

Because of its accelerated qualities and high tensile strength rating, Quick Set High Strength Concrete is ideal for gate posts, fence corner posts, structural supports and all other applications where a quick setting, high strength concrete is required.

Please note: Due to its quick setting qualities, Quickset High Strength Concrete is not suitable for slabs or jobs that require a smooth surface finish.

Now available in our all new weather resistant water proof packaging.

Application Instructions
  1. Ensure the hole does not contain any water (this product sets very quickly – water in the hole will cause product to harden before you are ready). Pour half the bag of dry concrete into the hole, around the post.
  2. Check the post is level and tamp down the dry concrete, creating holes to allow water penetration. Pour half of the water onto the concrete and tamp. Note: Water required is 2 litres per 20kg of Easy Mix Quick Set High Strength Concrete.
  3. Add the remainder of the concrete, tamp to create holes for water penetration, then pour the remainder of the water onto the mix. DO NOT STIR.
  4. Tamp the wet mixture, allowing water to flow down deep into the concrete. Always ensure your eyes are suitably protected.
Handy Hints

Warm and or / humid environments will reduce the work time of this product. To complete, keep the material cool and use cold or chilled water when mixing. This product should not be used in ambient temperatures below 7 degrees Celsius.


Post Hole Size
Width – at least twice the diameter of the post.
Depth – 1/3 of the length of the post (approximately 1/3 of the post in the ground) is ideal).


Easy Mix Quick Set High Strength Concrete will keep for up to six months if kept in a dry environment, off the ground and providing the bags remain sealed. High temperature and high humidity conditions may reduce the storage life of the product.
