Easy to handle and mix. I purchased this to do some filling and patching jobs and it was ideal. Good value for money for the DIYer

One bag was broken on delivery and not replaced - otherwise ok. Have used this concrete previulsy and it is good.

Works well, did everything it said it would. Bag isn't waterproof so consider that when storing.

I bought lots of these bags for my drive way, fence posts and even tile roof. Friendly to use. Good quality. Good consistency. Highly recommended.
Great product to use but these new bags always split open so I’ve ended up with concrete everywhere.
Wonderful product. Economical. Well balanced mix-consistency to produce the desired result: rock solid base. The instructions were concise, informative and helpful, ie 2.5 litres of water per bag was optimum. And the VME (volume measure estimate ie how much to use in the organised space) was close to correct. VME was 19 bags. We used 18.5. Wonderful.May I make a suggestion: On the front of the bag, where there is plenty of room, could you please print a series of 8 graphics? These would be user-friendly drawings that illustrate how to concrete a home job like a slab or path-way, ie ...1. Dig the recess to the desired size and depth. Pound the ground hard.2. Construct form-frame (20 mm wide timber) level and square, pinned with pegs every metre.3. Lay down ... MoreWonderful product. Economical.

Construct form-frame (20 mm wide timber) level and square, pinned with pegs every metre.3. Lay down plastic and then steel reinforcing.4. Mix 3 bags at a time (with 7.5 litres of water) in a wheel-barrow, or mixer.5. Pour, and with a straight-edge timber (20 x 70 mm), screed slowly, 3 times over.6. Leave for about 1 hr (hot day) to 4 hrs (cold day) till the surface is firm but soft (not yet hard dry).7. In circular motions, with a gliding action, carefully scrape over the surface with a float (or flat timber A5 size), then 30 mins later, with a trowel.8. Keep concrete area moist with a fine spray of water for slow drying.
Always used rapid set before with mixed results.Have lots of time for this decking build for myself so used this concrete for first time and am ecstatic I did.It mixed perfectly and pours beautifully and sets perfectly albeit you have to wait overnight but I know the finished result is perfect.
Handy size to put three bags in own mixer and not too expensive. For smaller jobs its perfect.
I purchased a bag of concrete... I was hesitant as it was a bit powdery, I didn't know what to expect! Thankfully, after reading the instructions and adding a dash of water, it worked out fine and my shovel is STILL stuck... Bravo! (Hey, you asked me to review a bag of concrete!)
I purchased it for repairing/patching the existing retainer wall. But this product is full of gravels, I realized I bought the wrong item.But I do agree it would provide a stronger support.
