Beschreibung
Zusammenfassung:	The invention discloses high-performance recycled concrete and a preparation method thereof. The high-performance recycled concrete comprises the following components in percentage by weight: 50-65% of recycled aggregate and 0.4-0.7% of a cross-linked polymer, wherein the molecular chain of the cross-linked polymer contains Si-OH bonds and organic amine cations. The recycled concrete is high in compressive strength and splitting tension strength, high in stacking density and low in slump. 本发明公开了一种高性能再生混凝土及其制备方法，所述高性能再生混凝土包括重量含量为50-65％的再生骨料、0.4-0.7％的交联聚合物；所述交联聚合物的分子链中含有Si-OH键和有机胺阳离子。该再生混凝土的抗压强度和劈裂张拉强度强，堆积密度高，坍落度低。
