quarry tile query

[Little5]

Whats the best cement or adhesive? Im relaying loose quarry tiles onto outside steps. they are currently cemented and the ice has broke them up over the winter. should I have to relay a cement sceed, before laying back down the tiles? if i use cement should I use the cement as a grout?

Are they all loose or just the odd ones

[Little5]

Its 3 steps each 6 feet wide. about 25% are loose

What concerns me is a quarter of the tiles are loose, at a later date others may become loose.

Any pics would help

I think its been the bad winter which has allowed some water to seep under the tile then when it iced up, it lifted them. I think the rest are quite solid although only an x-ray would be certain. hehe.
Im inclined to use a cement to put them back down, any views?

I would make sure the substrate is sound and a single part flexible adhesive and flexible grout
