摘　　要：需水量是影响砂浆、混凝土强度和耐久性的重要指标.再生胶砂需水量比能够较吸水率更全面地反映再生细骨料的胶砂工作性能差异.水泥品种和细骨料细度模数会对需水量比产生影响,在测定时需要规定水泥品种并考虑细度模数的影响.Water demand is important for strength and durability of the recycled concrete. Water demand ratio of recycled mortar is amore comprehensive technical index than water absorption to reflect the properties of mortar. As water demand ratio of recycled mortar is affected 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.

关 键 词：再生细骨料 再生胶砂需水量 需水量比
