Hello everyone,
I still need to build a concrete block retaining wall. At this location, I want to avoid using wall discs for cost reasons. To fill the blocks, I roughly estimate needing around 1.8 m³ (2.4 yd³) of concrete. Realistically, how much can two people manage to pour in one day if I rent a 140-liter (37-gallon) cement mixer from the hardware store and use dry concrete mix in bags? Unfortunately, I have no experience with this quantity or using a cement mixer. So far, we have only mixed smaller amounts in a bucket.

Benutzer 100110 Mar 2023 05:27I built 5 meters (16 feet) of wall with posts and filled it by myself.
That required two trailer loads of gravel. I started at 9 a.m. and finished at 3 p.m.
But you really feel it, especially since you have to fill the gaps between the stones and not just beside them.
Then, we built another wall about 25 meters (82 feet) long and 1 meter (3.3 feet) high along the neighbor's property. Two of us installed it using foundation cement and dry concrete in one continuous section.
I think we used around 3.5 cubic meters (124 cubic feet) of dry concrete with a retardant, delivered to us, dumped in a pile, and spread little by little over approximately 8 hours.

A concrete mixer is useful when there is a shortage of labor. It can mix quietly while you work on installing the previous batch.

Are those 2 big bags? More like 4 big bags of sand plus cement.
Or 150 bags of 25 kg (55 lbs) each.
Plan for a two-day job with two people.
I would have the material delivered in big bags from the building materials supplier. Picking up and loading 150 bags alone, plus disposing of the empty bags, would be a hassle.
A few extra dollars (around 60?) for delivery costs and a lot of saved effort. It will probably still be cheaper than buying bagged material.

WilderSueden10 Mar 2023 08:54Loading is usually not much of an issue. At hardware stores, you can reserve for pickup, and they will load the pallet directly onto your trailer using a forklift. This works quite well up to about 40 bags/1 ton (2,200 lbs); beyond that, the trailers are generally not strong enough.
I ran these numbers through a calculator—please ignore the costs. This is just about the quantities.
