From one book on masonry I get a mix for concrete as such:
1.6 cement :: 3.2 sand :: 6 gravelFrom another masonry book I get this for concrete mix:
5 cement :: 12.5 sand :: 20 aggregate or gravelFor mortar I get this as a mix ratio:
1 portland cement :: 1 lime :: 4 to 6 parts sandWhat 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 sandSo 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?
