None, as you know I conducted my own tests which I posted around two years ago, which confirmed the company's claims about increased flexural strength. In fact they exceeded them showing a 50% increase on samples of 30 and 50 mpa concrete on both fibre and non fibre samples cured for 28 days. I am not going to repost my results, but they were sufficient for me to believe the claims for reduced permeability without conducting my own tests and the improved consistency and flow produced is something that can be easily seen when working with a mix, something the forums detractors would have no clue about as you all refuse to try the product for yourselves.
