Abstract:Water demand is important for strength and durability of the recycled concrete.
Water demand ratio of recycled mortar is amore comprehensive technicalindex than water ab-
sorption to reflect the properties of mortar.s water demand ratio of recycled mortar is af-
fected by cement types and fineness modulus of recycled fine aggregate, cement varieties
should be fixed and the fineness modulus of recycled fineaggregate should be considered.
Key words:recycled fine aggregate;water consumption of recycled mortar;water consump-
tion ratio
