Its a white powdery substance caused by the salts in the material travelling to the surface and the water evaporating leaving the white powdery surface.Effloresence can be crystal like aswell and this happens when the material is wet the drys out and wet again and dry out ..this can happen when grouting if your over wipe the grout joints with a wet sponge.Hope this helps.
