Concrete mix supplied in 20kg plastic bags.

General Purpose Concrete mix is suitable for concrete bases, garage and shed floors, post erection, walkways, steps, patios backfill, infill, general repair work and other non structural applications.


The mix is a kiln dried, pre blended, factory produced prescribed concrete mix incorporating standardised binders and aggregates with a guaranteed cement content and mix proportions.

Mixing Instructions

  • To overcome any potential segregation that has occurred in transit, thoroughly mix the maxi bag contents before use.
  • The contents of the bag can be mechanically mixed in a free fall mixer for 3-4 minutes or hand mixed by pouring the contents of the bag onto a clean flat surface and slowly adding clean water in increments and mixing contiuously until the desired workability is achieved. For optimum results approximately 2.0 to 2.5 litres of clean water should be used per bag. Concrete should be used within 60 minutes of water addition.
  • Refrain from excessive water addition as this will weaken the the mix, delay setting times and adversely affect durability.
  • There is no need to add further additives or admixtures to the material on site as all required plasticizers/workability aids are already incorporated into the mix.

After Laying

For optimum results, the concrete should be cured for at least seven days after laying by covering with plastic sheeting or other suitable material. Similar measures should be taken where appropriate to protect the concrete from the effects of the sun, wind, rain and frost.


Each maxi bag of General Purpose Concrete will yield approximately 0.01m3 of fresh material when mixed using 2.0 to 2.5 litres of clean water.

    Bought 5 bags, 1 of which had some quite large pieces which had apparently got moist and set hard. Fortunately the rest of the bag mixed up OK. The bags had been stored as directed on the packaging.
