substituted for lime confrete, and that a standard
specification be set up for that.

I would like to say before that, that I would have the
ground underneath prepared by a ramming also specified,
or by the substitution for lime concrete now used, of
what is known as hardcore. Hardcore is really clean, dry
rubbish, and under that heading you might include broken
brick, broken stone, and any imperishable substances.
Would that be obtained and rammed down ?
17323
Yes. The object of that is to prevent waste of the
cement concrete, while it is going into soft places.
What do you mean by four inches of cement concreta, of
low grade? - What do you mean by low grade
I will give you the mixture. I will say one part of
cement. By cement, I mean a proper cement that will
stand.
