From one book on masonry I get a mix for concrete as such:
1.6 cement :: 3.2 sand :: 6 gravel
From another masonry book I get this for concrete mix:
5 cement :: 12.5 sand :: 20 aggregate or gravel
For mortar I get this as a mix ratio:
1 portland cement :: 1 lime :: 4 to 6 parts sand
What I am wondering is like a checkerboard or chess board where the
white squares are each one particle of portlandcement and the black
squares are each one grain of sand. And that the strongest and ideal mix
to make both Concrete and to make Mortar is simple this ratio:
1 portland cement to 1 of sand
So that each sand particle is connected to other sand particles by the
portland cement between them. Trouble is getting a mix so that it is
perfectly mixed as to result in a 3-dimensional perfect packing such as
a chessboard is a perfect 2 dimensional packing.
Has anyone done experimental tests to see at what ratio of
portlandcement to sand yields the strongest most durable concrete??
I would hazard to guess that if uniformly mixed that the 1 to 1 mix is
the strongest.
Is there any proof to my above assertion?
