20/11/17, 22 to 25 degrees, sunny to cloudy.
I ordered 2.1 meter of pre mix concrete to be delivered at 12.30pm, I got a call from this company to ask me if I want the delivery earlier at 10.30am. I said the form work is not ready, and keep the delivery on time at 12.30pm.
The delivery came on time, but the mix became unworkable in less than an hour time.
I suspect the mix was in the truck for too long.
