Abstract：According to the properties of shrinkage in dry condition and ex pansion in wet condition of fly ash bricks，an kind of special mortar for fly ash bricks was developed. The experimental results showed that it had characteristics such as good water protection, strong cohesiveness，rapid in tensity，low mobility，good mutability and so on. The mechanisms of prop erty optimization for the special mortar for fly ash bricks were discussed. Then it was applied in the real engineering.
