You said that in your experience, lime never auta ↑ 14.332
Never sets properly.
Now, have you in your specifications directed that 14333 when that concrete is laid it shall be rammed down,
until the lime comes to the surface ?
I have not.
Dont you think that if that were so, it would make ■14334
better floor ?
14335
No, I should say if you had good lime it would set better in the interstices of the concrete itself, because the air would get in and force setting, Under-
neath, it
uld still remain wet or dry into a powder. How do you account, Mr Lemm, with the inferior lime" we get in Hongkong, that in some cases we get lime that mets perfectly well and larts for years, and in etl.sr cases it never seems to get nå all, and is an you say
very inferior ?
I have never seen any good lime concrete myself.

14336 I have, where I have know it to last for years. They may have got good stone lime, and not mixed it
properly.

Dont you think it is to some extent due to bad mixing ?
Bad mixing, yes.
You said just now, when I suggested that if it were 14338 sufficiently rammed, so that the lime could come to
the surface, that it would not make a better floor. Do you know that that is laid down in either Kirst or
Molesworth ?
I have not seen it in either Hirst or Molesworth. I have both books, but I have not seen it. It is said that the outer surface will set, but the inner surface will simply dry to powder and will not set at all. Do you have it rammed at all 7
