Test results updated to this morning.

Results updated to 21 October

Data updated today.

Latest data updated Tuesday 7th October.
Some of the 7 to 28 day growths are quite variable. If I am supplied with a little further data I can make
predictions of the growth expected before the cement is used. I would need details such as free lime, C3S, LOI and filler content. A typical relationship between actual and predicted 28 day strengths is shown on the left. Further information is on my website http://www.arthurharrisson.com/quality.html

Back now after successful presentations to conferences in Stratford-upon-Avon and then Istanbul. Latest cement results below.
