With your kind indulgence, I'd like to pick up the points in your suggestion that leave me with some doubts. First of all, the use of 'lixivation': I've always seen this in the sense of certain elements being washed out of a substance: this is the sense in your ref. to 'lessivage des hydrates' — BUT this is not what is being referred to in this context! It actually refers here to the way the cement as a whole can be 'washed out' — the sense is more that of being 'washed away'. I don't know if 'lessivage' is more along those lines, but I suspect not. Think of situations like severe floodwater 'washing out/away' the foundations beneath houses. In term of concrete vs cement, I don't see why using 'concrete' here in EN would be any less or mor ambiguous than using 'cement'? If I understand the context properly (boring holes for fracking), I'm pretty sure that what is pumped around the liner is literally cement, rather then any form of concrete (though I'm happy to be proven wrong on that point!) |
