NEED wall filler that can be drilled for fixing a shelf

[fordham]

I and Fixing some shelves the ones with the long slotted strips that allow you to place the shelves at variable heights from Tegmetall. One of the holes i driilled was straight into the cement work between the bricks. The hole is quite big probably larger than a fifty pence sized hole and about 2 inches deep(I tried to use a nine inch nail and fixing but that didn't work and only made the hole bigger ). what can i use to fill this rather large hole that will provide a secure fixing for my rawplug and screw to hold the shelf. i have managed to drill the other 14 holes correctly without much problem and do not want to drill another 5 holes if i move this last upright. please help!! any suggestions would be very much appreciated.
