I spoke to the concrete company about the water and they said that the volumetric mixers auto adjust the water cement ratio so it ensures the ordered specification.
Pump was supplied by the concrete company. I think it's been a long day and when things don't go smoothly, you wonder what other corners may have been cut. Damn, I'm catastrophising again.
I'm sure it's fine. They are 525mm thick. I've asked the company to provide exact details of the 3 loads, as I want to know exactly what they did. I won't hold my breath though.
I was wondering if I should cover the concrete and be mixing it or should I simply leave it. The brickie is scheduled to start laying on Thursday?
That's interesting. We never requested extra water and I've just checked the ticket and the driver checked that box. My wife who had nothing to do with the pour, signed it without thinking 😮💨
I just asked for C25 and as we used a pump, I assumed they'd do the mix accordingly as it was clear it was for footings. It was a volumetric supply and mixed on site, not ready mixed.
Just looking at the ticket and they ticked extra water added via customer request. We never requested extra water be added and I'm not sure if this is the default when you use a pump?
We got it sorted eventually and the two final trucks arrived together, but the buggers fleeced us and the driver went to my wife and she signed the ticket and we apparently used 29.5 M3, but my calculations were 24m3
Order the concrete and was told that there would be two trucks arriving. One truck turns up pours and then we’ve been waiting an hour and still no second truck. We’ve covered up the concrete, but I’m getting concerned now.
