Use an anonymous supper plasticiser plant (rhetorical question - NNTR)?
Please let the forum know the outcome of the now-overdue telephone call to RMC about the options.

It is a little disappointing that the original poster is anonymous as it appears there is scope for some dialogue using the Personal Messaging function of this site rather than the posting function. Some dialogue there might work wonders, however as the original poster is anonymous, that cannot happen.

"Admixtures are classed according to function. There are five distinct classes of chemical admixtures: air-entraining, water-reducing, retarding, accelerating, and plasticizers (superplasticizers). All other varieties of admixtures fall into the specialty category whose functions include corrosion inhibition, shrinkage reduction, alkali-silica reactivity reduction, workability enhancement, bonding, damp proofing, and coloring. Air-entraining admixtures, which are used to purposely place microscopic air bubbles into the concrete, are discussed more fully in Air-Entrained Concrete. "
"Superplasticizers, also known as plasticizers or high-range water reducers (HRWR), reduce water content by 12 to 30 percent and can be added to concrete with a low-to-normal slump and water-cement ratio to make high-slump flowing concrete. Flowing concrete is a highly fluid but workable concrete that can be placed with little or no vibration or compaction. The effect of superplasticizers lasts only 30 to 60 minutes, depending on the brand and dosage rate, and is followed by a rapid loss in workability. As a result of the slump loss, superplasticizers are usually added to concrete at the jobsite. "
I had enough problems with the Ready Mix Concrete plant in the vicinity spilling polystyrene beads used for making light weight concrete. No help from my side.

The process is probably commercially sensitive, meaning that no-one who already makes it is going to reveal the process for fear of loss of market share.

Especially if
you've just been fired from a building site. Chuck a bag in to the drum of a
RMC wagon as you walk off site, the concrete will never set.
