Last week we held the first Controlling Concrete Quality day which was very well received by the participants and which inspired some very interesting and informative discussion. The attendees came from cement production, ready mix, concrete products and admixtures and the exchange of experiences was helpful all round.

I would anticipate holding a second day in the autumn. If anyone has an interest in attending I would be pleased to hear from you - arthur.harrisson@btinternet.com .

The charts below were updated this morning Tuesday 8th July.
