Adbri General Purpose Concrete
Add water. Nominal 25MPa.
Adbri General Purpose Concrete is sand, cement and aggregate pre-blended in a 20kg bag — add water only. The bag prints a nominal 25MPa and lists pathways, posts and making slabs. It is the load-rated bag of the two, where Rapid Set is explicitly not.

Real stock, not a swatch. Blended products vary a little batch to batch, so treat these as a guide rather than an exact colour match.

What Adbri General Purpose Concrete suits
What can you use Adbri General Purpose Concrete for?
Pathways
The bag's first listed use. A path is small enough to be a bagged job and permanent enough to want a rated mix.
Setting posts
Where you would rather have the strength than the speed. A post carrying anything wants this bag, not the Rapid Set.
Making slabs
Small pads and slabs where a truck is not worth calling but the concrete still has to carry something.
Bases and repairs
Bases for tanks, bins, air conditioners and pumps, and patching where an existing slab has gone.
How many bags of concrete?
Count backwards from the pour
Work out the hole or the slab first — length by width by depth, in metres, multiplied together gives cubic metres — then divide by what a bag yields. The yield is printed on the pack.
Bagged concrete runs out of economic road faster than people expect. Anything much past a small pad is cheaper as loose aggregate and cement, or delivered pre-mixed, and we will tell you where that line falls.
| Job | The volume | Worth knowing |
|---|---|---|
| A fence post hole | Depends on the hole | Dig one and measure it. Post holes vary far more than people expect. |
| A small pad, 1m x 1m x 100mm | 0.1 cubic metres | Comfortably a bagged job. Divide by the yield on the bag. |
| A shed floor, 3m x 3m x 100mm | 0.9 cubic metres | Stop — ring us. Loose or delivered is far cheaper at this size. |
Wet cement and lime burn skin, and the burns are delayed so people often do not notice at the time. The dry dust contains crystalline silica. Gloves, eye protection and a P2 mask, every time.
Why Adbri General Purpose Concrete
Why choose Adbri General Purpose Concrete?
Nominal 25MPa, printed on the bag
A specification rather than a general claim about being strong. That is the difference between this and anything sold on convenience.
Add water only
Sand, cement and aggregate already proportioned. No sourcing three materials and no guessing at the ratio with a shovel.
It is the load-rated one
Rapid Set says NON-STRUCTURAL on the pack. This one does not, and it carries a strength figure. That is the whole distinction.
One bag size, so the sums are simple
20kg, and pallets on request. Work out the cubic metres, divide by the yield on the bag, and order a little over.

Using Adbri General Purpose Concrete
How to use Adbri General Purpose Concrete
Work out the volume of the pour
Length by width by depth in metres gives cubic metres. Work out how many bags from the yield on the pack, and order over — running short mid-pour leaves a cold joint you cannot undo.
Add water and mix thoroughly
The quantity is printed on the bag. Too wet weakens the concrete, too dry and it will not compact properly.
Place and compact out the air
Work it into the corners and rod or vibrate the air out. Air voids are where a slab fails and they are invisible until it does.
Keep it damp while it cures
Concrete gains strength over days and needs moisture to do it. A slab left to dry out in a Perth summer is measurably weaker.
When to choose something else
When it is the wrong product
- Past a few bags this gets expensive. For a real slab, loose Concrete Mix plus cement, or pre-mixed delivered, costs a great deal less by volume.
- 25MPa is a nominal figure for a bagged mix you are proportioning water into on site. Anything engineered wants an engineered mix and a conversation, not a pallet of bags.
- The 28-day figure is a 28-day figure. Concrete is not at full strength the day after you pour it, whatever it feels like underfoot.
- Wet cement and lime burn skin, and the burns are delayed so people often do not notice at the time. The dry dust contains crystalline silica. Gloves, eye protection and a P2 mask, every time.
