I came accross this last week too. Neither the supplier, (Eastbrook) nor the
manufacturer would comment other than to reiterate that an anti-crumble agent
was necessary. They referred me to the cement manufacturer. I spoke to the
Technical Director of the major manufacturer who, like me, (30 years in the
trade) had never heard of such an additive. I will be writing to the supplier
and tray manufacturer complaining about their spurious directions and will
report back if there is any interest still on this string.

I might wander back in another couple of years and continue the
conversation.
