Fly Ash-Desulfurization Gypsum Mortar and Concrete Part II: Performances
FA-FGD mortar and concrete were manufactured and tested the main performances. With WFA-FGD taking 80~85% of the total composite binder by mass, mortar used in buildings was provided with good workability, enough mechanical properties specified for masonry in China, low drying shrinkage and strong sulfate corrosion, which was suitable for plastering or coating inside and outside walls. With LFA-FGD more than 30% in proportion, middle-strength concrete showed satisfactory workability with no segregation, no bleeding and low slump loss, stable strength development and low brittleness, about 60% of the domestic standard limit of wear mass loss in the specified test, good impermeability as well as excellent cracking resistance.
