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.
