What percentage of unconfined surface area is allowable during placement of a non-shrink grout?
I am aware that non-shrink grouts need to be confined when placed, perhaps with a grout-box around a baseplate. However, a grout-box has unconfined surface area in the space between the baseplate...
The following scenario lead me to my eventual question:
A field technician is casting C-1107 hydraulic cement non-shrink grout specimens into 2X4 cylinder molds for compressive strength testing..(I have only used 2X4 molds for desktop pencil holders but I digress). The breaks are coming up...
