Hello
I am going to build a room using concrete form blocks. The floor slab is about to be completed.
I will be using concrete blocks measuring 50x25x30 cm (20x10x12 inches). Reinforcement is clear. I would like to mix the flowing concrete myself. A concrete mixer is available.
Now the questions: Which aggregate size should I use for the concrete? What is the mixing ratio (aggregate to cement)? What additives are necessary to achieve flowing concrete? Is the concrete truly "self-compacting," or will I need to assist with a tamping rod or a vibration device?
I need 200 liters (53 gallons) of concrete per square meter of wall surface.

Oh, was that you with the 5x5x5m (16x16x16 ft) hole dug by the excavator?
Instead of building the formwork with concrete blocks, you could also form the walls and pour the concrete directly. Alternatively, you might consider building with sand-lime bricks. Either way, waterproofing needs to be done.

Hello Jochen104
I have read the thread as well. How do you come to the conclusion that it was me?
Sand-lime brick is too expensive for me. Cavity walls are too complicated. Formwork blocks are the easiest for me to work with.
I am building a waterproof concrete basement.

Hello Steven / Stefan?!?!
Sorry, I only had something about a vaulted cellar in mind there. But I must have mixed that up. Please excuse me.
Okay, I thought that using calcium silicate bricks might be more cost-effective. Have you compared all the costs? Concrete (cement, gravel, and water), bricks, steel, and labor?
