Concrete frustration

On the Jubilee Way run this morning, somewhere on the Ewell by-pass, I was passed by a serious tanker lorry containing concrete additive. A white lorry which I thought said CONTAIN and BUILD CENTRE. Not having come across additives being used or distributed in such large quantities, I thought I would check, drawing a more or less complete blank, with both Bing and Google declining to provide a list of proprietary names of such additives, just articles about concrete additives in general.

But one of them turned up reference 1, suppliers of large additive tanks for ready mix concrete suppliers like the people at reference 2, who, as it happens, talk about admixtures as well as concrete, producing millions of litres a year of the stuff. The tank in question being the black tank right of centre, rather than the grey hopper, probably cement. So I have confirmed that these additives are produced and used in large quantities. And I now know what a 'bund' is. 

PS: registration plate No.34 is proving as elusive as No.26 before it, although I did manage a No.36 yesterday and a No.31 today.
