I saved Four of these today, they were on the way to the local tip or scrap yard. I dont know what they are but I am thinking I could make a couple of small metal casting boxes with them. They are about 6 inches square.

150mm concrete test cube moulds and tamping bar.
About £800 to buy that set new. Looks unmolested too.

Is that for the slump test I'm thinking?

No for a compression test once set if I remember correctly correctly. That’s how they get the C30/C35 etc figure

A slump cone is used for the slump test. These are for sampling concrete, then curing and crush testing to make sure concrete is to spec.
I used to crush at 7 days, 14 days and the last 2 at 28 days - tests the early strength of concrete so you could strip shutters early for suspended concrete slabs/beams etc.

They are made to some stupid tight tolerance. £800 would be pants-down-new price.A quick search on the auction site throws up from 50 quid each upwards so in the intrest of making some cash for a digger bucket
They look in really good nick. 19mm spanner for the nuts.

Yep, concrete crushing cube moulds. You make the cubes and send them in for crushing at specified periods as mentioned above.
You do't usually buy them, what you do is hire them (or get them on free loan from the testing company). Someone's going to be sorry that they got left behind - the hire might be cheap but the replacement cost certainly isn't. That's why they sell so well on eBay - better to buy them for 50 quid than replace them for 500.
