Concrete BS8500-2
I hope this doesn't post twice - I posted this a minute ago but it seeme to have vanished.
Does any one have an electronic copy of BS8500-2 (Concrete specifications)
I really just need to have a look at table 12 on page 21 I think

I don't think concrete would be good for the power to weight ratio mate.
Sorry i just could not resist.
Who the f**K tightened this up!

Looks strange to me.
Where abouts are you putting the concrete in your car???????

Thanks for the replies.
I guess a bit of concrete weight might make a seven more stabe.
Actualy, it's nothing to do with cars, I've been given a specification for some repairs to my house that refer to an ST2 concrete
specification. This gives the mixture in weights of cement, sand and agregrate. It's a bit hard to weigh such big weights. Apparently table 12
in the British standard document tells how to do it by volume.
I was sort of hoping there might be an engineer out there with a copy of the document.
The 16sea.pdf document isn't it but thanks anyway

Have you tried the library at you local technical college. They often keep a good selection of British Standards for the use of students. The bigger
the college the more likely they are to have them.
Oh, and you'll probably need to use a student to get it.

What are you doing Jon, underpinning? You could ask at a concrete factory if you have one local, they should know the volumes.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Pete, I have to rebuild a small part of a hundred year old extension that was never properly built. The concrete forms the foundation to a brick
pillar. My engineer has calculated the loads and given me a design to implement. I'll get him to give me the missing page from the BS8500 spec

Concrete
According to Barnes & Mander - Farm Building Construction ST2 mix is 50kg cement, 160kg sand, 240kg 20mm aggregate, yielding 0.21 m3.
By volume 4 parts cement to 9 parts sand and 15 parts 20mm aggregate.
I'm only quoting the book, so don't blame me if the house falls down. Just bear in mind when the guys were building the house in 1700 and
fast asleep they hadn't even invented kg.
