Hydraulic Mortars Made by Lime, Brick Sand and Fly Ash

In this research work we consider the behaviour of lime-based hydraulic mortars with sandy aggregate obtained by brick crushing. This aggregate simulates the features of "special waste", as broken bricks caused by building demolition. Moreover, fly ash, coming from bio-mass combustion plant, has been added to the sandy aggregate. The high compression resistances for brick mortars indicate a good hydration process, due to pozzolanic reaction of the both, brick sand and mixture of brick and fly ash sand. The fly ash-based mortars have been submitted also to the leaching tests with water in order to highlight the possible release of salts.
