Mortar used in building materials, prefabricated construction elements for repairing and sealing bridges, comprises calcium sulfoaluminate cements, siliceous aggregates and water

Abstract

Mortar comprises calcium sulfoaluminate cements, siliceous aggregates and water, where siliceous aggregates are partially substituted by carbonate containing fly ash. The fly ash from incineration of municipal solid waste replaces the siliceous aggregates up to 90wt.% relative to the total weight of siliceous aggregates. USE - Mortar used in building materials, prefabricated construction elements and civil engineering for repairing and sealing bridges, airport runways and garage ramps (all claimed). ADVANTAGE - The mortar enables to increase durability and chemical resistant property of building materials.
