How to check if the concrete is okay?

[Projektmannen]

Today I went to Byggmax and bought several bags of fine concrete. When I got home and opened the first bag, there were hard lumps mixed with loose concrete. I suspect the bags were mishandled at Byggmax, but they don't want to acknowledge that. They suggested it's the customer's responsibility to check that the bags don't contain any hard lumps???? I wonder how that's supposed to work? I can't open the bags at Byggmax. Luckily, there were lumps in the first bag I opened. The job I was doing required freshly mixed concrete all the time, so I was lucky to discover the problem in the first bag. I returned with all the bags, although they were initially reluctant to exchange the others. I then went to another company that felt more reliable for buying concrete. But the question remains, how could I check that Byggmax concrete had lumps? Anders, Värmdö

Now I don't know how bad it was. A bag that's been exposed to a lot of water can of course absorb some (even though they are usually plastic-coated) and then the concrete hardens. It's normal for there to be some lumps that quickly fall apart when you pour it into your mixer and doesn't mean the concrete won't work.

The short answer is, just as you have pointed out yourself: It can't be done. If the bag is rock hard, then it's obviously a different story.

I don't know how it looks at "your" byggmax, but here they store the bags so that in bad weather they tend to blow in. Hornbach is better as they have everything in the hall, safe from weather and wind.

Switch supplier and brand.

Finja's concrete has been delivered for a year or two in relatively dense plastic bags that are not moisture-sensitive. Much better than paper with a little internal plastic.

Finjas concrete has been delivered for a year or two in relatively airtight plastic bags that are not moisture-sensitive. Much better than paper with a bit of internal plastic.

Hi, yes you are absolutely right and that's what I did too.
But then it's also the case that if you can't handle concrete, you shouldn't sell concrete.
And I still don't know how to check a concrete bag, if it is hard and ruined or okay

I still don't know

I think we agree. You can't control bags with lumps in them, where the concrete has set.
In any case, I've learned to choose a different supplier than Byggmax.
