Concrete Cube Size?
Concrete Cube Size?
(OP)
I've been carrying out some research on a new cement formulation. For various reasons the test blocks are 50mm cubes.
From some reading I've done the size of the test cubes affects the compressive strength results.
Is there a standard equation that's used? Can anyone recommend a good piece of literature that relates changes in sample size to cube strength. I've done some research but I haven't come up with anything definitive.

To use other cubes sizes and then try to compare based on correlation studies is not comparing apples to apples.

Doesn't matter that much.

You post, though, said Concrete Cube size. This makes me wonder if you are testing "cement" - the cementitious materials or do you want to test concrete made with your cement formulation - in the latter, usually 150mm cubes are used (BS and IS standards). USA/Canada/Europe use cylinders.
You might like to get a copy of Neville's book on Properties of Concrete or Neville and Brooks' book on Concrete Technology. These might help you. If you want a book dealing with concrete cubes, M.S. Shetty's book is likely the best.
