We wanted a solid foundation, but screwed up the concrete. The master tells how to DO NOT

- Hi, Volodya. I see that the foundation has already been filled. Well done! Will you build a house soon?

- You know, Kolya, at first I wanted to mix the concrete itself, and then I counted and ordered a ready-made mixer. I phoned RBU and chose where the price is the least. It's cheap, but the people work there are cool. The mixer driver literally saved my foundation.

- And what happened?

- I didn't expect such good concrete to be brought. Poured into the formwork, and it grasps before our eyes. I did not have time to accept and level. How strong. The driver looked at how I was tormented and suggested: "Let's add a little water to the solution, it will become more mobile, it will be easier to work." You know, it helped. The masters know their job.

- Hmm, the driver did you a disservice. What grade was the concrete?

- I ordered the M250. I consulted with the designers. No more needed for my house.

- Well, what can I say? Congratulations, now your house will stand on a foundation made of concrete of the brand M150. Do you think it will withstand, will not crack over the years?

- Wait, how is the M150? Don't fool my head. There is even an invoice, everything is written there: M250!

- Let's start with your savings. You ordered concrete P1 or P2. There is less water and less cement. That is why it is cheaper. But tough. It is difficult to lay it.

- Well, to hell with him. Water was added. After that, everything was fine.

- Vova, one of the most important parameters when calculating the composition of concrete is the water-cement ratio. If more water is added to the same amount of cement, it will not react. The concrete will be porous and less durable. If there is less water, not all of the cement will react, which will also reduce the strength of the concrete.

- What do you mean by that?

- Yes, I already told you everything. As soon as you added water, the grade of the future concrete of the foundation dropped dramatically.

- And now what i can do?

- You can go to church, pray and light a candle so that everything will be fine with you. You can build one floor instead of two.

- This is what I got, of course. I will look for some way out of the situation. But there is still so much work ahead of building a house. Nikolay, do you mind if I first come to you for advice? You're a construction worker, you know everything.

- I will help you with advice, of course. But, alas, it is impossible to know everything. Look, there is a "Repair Chips" channel on Zen. There is a lot of useful information. If you had read this article before, would you have made this mistake? The presentation of the material is also cool there. It seems that I just read the story, but the information in my head was deposited. Will come in handy someday. So that subscribe right now, otherwise you'll be looking for this channel later. By the way, if you like a post, the Zen algorithm remembers it. Then he recommends you more such useful articles. Don't hesitate, press your finger up. 👍
