60 lb. Concrete Mix

adding 2.3L/30kg bag could yield really dry mix in some conditions and work ability is not great, however bag says can add up to 3.5L of water per bag as max max. just not sure what is the final PSI when using 2.3L vs 3.4L. otherwise there is no mention about air entrain content in it. I used it for an outdoor pizza oven slab and also for grouting. mixed two bags at a time with set delay, air entrain, and poly 1" fibre. for grout I use more water, about 5.6 liters per 2 bags and for slab I sued just above 2.3L per bag( ~4.5L per two bags) but I really had to give a splash to the mixer sometimes, the vibrator wont bring much cream for the slab as it does for the grout, I wish I could tell what psi is for each water amount so I can design my mix properly . the result was a slab surface which is a but rough when I followed the 2.3L recommendation

But the mixtures in each bag are different. Some bags contain little cement.

For crosswalks or build basement doable wall

Worked perfect as a pad for some masonary stone steps I needed to land infront of the house.

Easy to use, add water, mix and pour. Great for pads, curbs, firepit or other DIY projects.

Perfect for filling the sono-tubes for the deck job.

Works as expected

Needed a border for my garden, and this worked perfectly, added water, poured it into my plywood mould and it’s perfect

The price is awesome and that’s why I purchased to be honest. I’m using this to make concrete crafts so I need to sift out all the gravel and there’s a lot … about 1/3 gravel. Mixed with shredded news paper white glue and water I turn the mix into clay and mold away

Easy mixing, 2 min in cement mixer. Make sure to rent one if you are using more then 6 bags, it is worth every penny and will save you back.
