摘??要:設計了27個配合比,研究了不同種類及摻量的減水劑對再生細骨料砂漿基本工作流變性能與力學性能的影響。結果表明,當粉煤灰摻量為20%時,摻0.55%、0.65%、0.75%的聚羧酸減水劑再生砂漿的2h稠度損失率和28d抗壓強度分別為20.18%、17.67%、14.89%和18.1MPa、19.2MPa、20.5MPa,均優于同等摻量下的三聚氰胺減水劑和萘系減水劑。?Abstract:?27mixratios?weredesignedtostudytheinfluenceofdifferenttypesanddosagesofwater-reducingagentsontherheologicalpropertiesandmechanicalpropertiesofrecycledfineaggregatemortar.Theresultsshowthatwhentheflyashcontentis20%,the2hconsistencylossratesand28dcompressivestrengthsofrecycledmortarswith0.55%,0.65%and0.75%polycarboxylatewaterreducerare20.18%,17.67%,14.89%and18.1MPa,19.2MPaand20.5MParespectively,andaresuperiortothosewiththesameamountofmelamine-typeandnaphthalene-typewaterreducer.
